_______________
Notes to Performance Information and Expense Information:

All performance and expense information provided is as of the day prior to 
the Initial Date of Deposit.

(1)  The actual returns an investor will receive will vary due to the 
maturity, redemption, exchange or sales of Bonds, changes in fees and 
expenses, changes in interest income, the market value of the Bonds on the 
date an investor purchases Units and how long Units are held.  See "Estimated 
Long Term Return and Estimated Current Return" in Part B of this Prospectus 
for information concerning how Estimated Returns are calculated.

(2)  The Public Offering Price will vary from that shown above due to changes 
in the prices of the underlying Bonds subsequent to the Initial Date of 
Deposit.  In addition to the Public Offering Price, investors must also pay 
accrued interest from the preceding Record Date to, but not including, the 
date of settlement (normally three business days after purchase).  For Units 
purchased on the Initial Date of Deposit, $.____ of accrued interest will be 
added to the Public Offering Price.  See "Public Offering Price" and "Accrued 
Interest" both in Part B of this Prospectus for further information.

(3)  The Estimated Income figures reflected above are estimates determined as 
of the business day prior to the Initial Date of Deposit and actual payments 
may vary.  It is anticipated that the amount of interest to be distributed 
per Unit in each year will initially be substantially equal to the Estimated 
Net Annual Interest Income per Unit provided.  The amount of interest to be 
distributed annually per Unit, will generally change as Bonds are redeemed, 
mature or are sold or as fees and expenses increase or decrease.  See 
"Distributions to Unitholders" in Part B of this Prospectus.

(4)  The Average Weighted Maturity of the Bonds in the Trust is calculated 
based upon the stated maturities of the Bonds in the Trust (or, with respect 
to Bonds for which funds or securities have been placed in escrow to redeem 
such Bonds on a stated call date, based upon such call date).  The Average 
Weighted Maturity may increase or decrease from time to time as Bonds mature 
or are called or sold.

(5)  The sales charge is reduced for certain purchasers and for single 
transactions of at least 500 Units or $50,000 (whichever is more favorable to 
the investor).  See "Sales Charges" in Part A of this Prospectus and "Public 
Offering Price" in Part B of this Prospectus.

(6)  The Trustees Fee and the Sponsor's Evaluation and Surveillance Fees are 
per $1,000 principal amount of the underlying Bonds in the Trust.

(7)  The Trust (and therefore Unitholders) will bear all or a portion of its 
organizational costs (but not the expenses incurred in the printing of 
preliminary and final prospectuses, nor the expenses incurred in the 
preparation and printing of brochures and other advertising materials or any 
other selling expenses), as is common for mutual funds.  See "Trust Operating 
Expenses" in Part B of this Prospectus and "Statement of Condition."

                                TRUST STRATEGIES

                               INVESTMENT OBJECTIVE

The Trust is designed to provide a high level of current income and 
preservation of capital.  The Trust may be an appropriate investment vehicle  
for investors who wish to participate in a portfolio of taxable fixed income 
obligations issued by utility companies with greater diversification than 
investors might be able to acquire individually.  There is no assurance that 
the Trust will achieve its investment objective.

                              INVESTMENT PHILOSOPHY

The Trust is a non-managed investment vehicle and employs a buy  and hold 
investment strategy.  The Trust plans to hold to maturity a portfolio of ____ 
corporate debt obligations.

                              INVESTOR SUITABILITY

The Trust is a suitable investment for investors seeking to:

 . Earn regular monthly income;

 . Obtain greater portfolio diversification than may be possible individually;

 . The Trust is also available to foreign (non-resident) investors who seek 
income that is exempt from U.S. withholding, provided certain conditions are 
met.

The Trust is not a suitable investment  for individuals seeking to:

 . Pursue an aggressive high-growth investment strategy;

                       HOW THE TRUST SELECTS INVESTMENTS

The Trust consists of a portfolio of insured corporate debt obligations 
issued by utility companies which have a dollar weighted average maturity of 
___ years.

 In selecting corporate debt obligations (the "Bonds") for deposit 
in the Trust, the following factors, among others, were considered by the 
Sponsor:  (a) the prices and yields of such Bonds relative to other Bonds of 
similar quality and maturity, including the extent to which such Bonds are 
traded at a premium or discount from par; (b) the present rating and credit 
quality of the issuers of the Bonds and the potential improvement in the 
credit quality of such issuers; (c) the diversification of the Bonds as to 
location of issuer; (d) the income to the Unitholders of the Trust; (e) 
whether the Bonds were issued after July 18, 1984; and (f) the stated 
maturities of the Bonds.  A description of the Bonds included in the Trust is 
set forth in the "SCHEDULE OF INVESTMENTS," below.

                                RISK FACTORS

An investment in Units of the Trusts should be made with an understanding of 
the risks which an investment in fixed rate corporate debt obligations may 
entail.  These include credit risks and the risk that the Bonds and therefore 
the Units will decline, and may decline precipitously, with increases in 
interest rates.  Although in recent years interest rates have been relatively 
stable, the high inflation of prior years, together with the fiscal measures 
adopted to attempt to deal with it, have resulted in wide fluctuations in 
interest rates and, thus, in the value of fixed rate debt obligations 
generally.  The Sponsor cannot predict future economic policies or their 
consequences or, therefore, the course or extent of any similar market 
fluctuations in the future.  General problems of utility company issuers 
include the imposition of additional federal, state and municipal 
governmental regulations, increased costs attributable to environmental 
considerations, the difficulty of the capital market in absorbing utility 
debt, the difficulty in obtaining fuel at reasonable prices and the effect of 
energy conservation.  As such, there is no guarantee that the Trust will 
achieve its objectives.  See "Risk Factors" in Part B of this Prospectus. 

Certain of the Bonds included in the Trust may be original issue discount 
bonds or "zero coupon" bonds, as noted in each "SCHEDULE OF INVESTMENTS."  
These Bonds are subject to greater price fluctuations with changing interest 
rates and contain additional risks set forth in "RISK FACTORS" in Part B of 
this Prospectus.

DISTRIBUTIONS AND TAXES

                                 Page 5 of 10


<PAGE>

INTEREST AND PRINCIPAL DISTRIBUTIONS

The Trustee of the Trust (The Chase Manhattan Bank) will collect principal 
and interest on the Securities as it comes due and hold such amounts for 
distribution to Unitholders.  The amount of the Net Annual Income per Unit 
set forth under "Performance Information - Estimated Interest Distributions" 
assumes that all of the Bonds are delivered to the Trust.  See "COMPOSITION 
OF TRUSTS" appearing in Part B of this Prospectus.  Interest income does not 
include accretion of original issue discount on "zero coupon" Bonds.  See 
"RISK FACTORS" in Part B of this Prospectus.  Distributions of income will be 
paid by the Trustee to Unitholders on the fifteenth day of each month to 
Unitholders of record on the first day of such month.  Distributions of 
principal will be paid on the fifteenth day of the each month to Unitholders 
of record on the first day of such month, provided the amount available for 
distributions equals at least $0.10 per Unit.

The amount of interest you will receive on an annual basis will be reduced by 
the expenses of the Trust and will generally change as Securities mature or 
are sold or as fees and expenses increase or decrease.  

                                    TAX STATUS

For non-resident aliens, income from the Trust will be exempt from 
withholding for U.S. federal income tax, provided certain conditions are met. 
 See "TAX STATUS" in Part B of this Prospectus for further tax information.

                              INVESTING IN THE TRUST

                                  SALES CHARGES

The maximum sales charge of   % applies only to purchases of less than 500 
Units.  Sales charges for larger single transactions during the primary 
offering period are as follows:

                           PRIMARY MARKET SALES CHARGE

*Breakpoint sales charges are computed both on a dollar basis and on the 
basis of the number of Units purchased, using the equivalent of 500 Units to 
$50,000, 2,500 Units to $250,000 etc., and will be applied on that basis 
which is more favorable to the purchaser.

The sales charge assessed on Units sold in secondary market transactions is 
determined in accordance with the table set forth below based upon the dollar 
amount purchased and the Weighted Average Maturity of the Trust:

_______________

(1)  The Sponsor's contracts to purchase the Bonds were entered into on 
_________, 1997.  All Bonds are represented by regular way contracts, unless 
otherwise indicated, for the performance of which an irrevocable letter of 
credit has been deposited with the Trustee.

(2)  A brief description of the applicable Standard & Poor's and Moody's 
rating symbols and their meanings is set forth under "DESCRIPTION OF RATINGS" 
in Part B of this Prospectus.  "N.R." indicates that the issue has not been 
rated by that rating agency.

(3)  Under this heading, the year in which each issue of Bonds is initially 
or currently redeemable and the redemption price for that year is shown.  
Unless otherwise indicated, each issue continues to be redeemable at 
declining prices thereafter, but not at a price below par value.  The prices 
at which the Bonds may be redeemed or called prior to maturity may or may not 
include a premium and, in certain cases, may be less than the cost of the 
Bonds to the Trust.  In addition, certain Bonds in the portfolio may be 
redeemed in whole or in part other than by operation of the stated redemption 
provisions under certain unusual or extraordinary circumstances specified in 
the instruments setting forth the terms and provisions of such Bonds.

(4)  During the Initial Offering Period, evaluations of Bonds are made on the 
basis of current offering side evaluations of the Bonds.  

(5)  This Bond has been purchased at a deep discount from the par value 
because there is no stated interest income thereon.  Bonds which pay no 
interest are normally described as "zero coupon" bonds.  Over the life of 
Bonds purchased at a deep discount the value of such Bonds will increase such 
that upon maturity the holders of such securities will receive 100% of the 
principal amount thereof.

(6)  Other information regarding the Bonds in the Trusts on the Initial Date 
of Deposit is as follows:

                                                       Annual
                                           Profit     Interest    Bid Price

In addition, the difference between the Trustee's determination of Offering 
Price and Bid Price (as a percentage of principal amount) is ._____% for the 
Trust.

_______________

(1)  Represented by contracts to purchase Bonds which include "when issued" 
or "regular way" or "delayed delivery" contracts for which an irrevocable 
letter of credit issued by a major commercial bank has been deposited with 
the Trustee on the Initial Date of Deposit.  The amount of such letter of 
credit and any cash deposited exceeds the amount necessary for the purchase 
of the Bonds plus accrued interest to the Initial Date of Deposit.  At the 
Initial Date of Deposit, Securities may have been delivered to the Sponsor 
pursuant to certain of these contracts; the Sponsor has assigned to the 
Trustee all of its rights, title and interest in and to such Bonds.

(2)  Aggregate value (at offering prices) as of the Initial Date of Deposit 
of the Bonds listed under "SCHEDULE OF INVESTMENTS" herein, and their 
aggregate cost to the Trust is the same.  Such offering prices were 
determined by Kenny S&P Evaluation Services, a division of J.J. Kenny Co., 
Inc., as of the close of business on the business day prior to the Initial 
Date of Deposit.  (See "EVALUATION OF BONDS AT THE INITIAL DATE OF DEPOSIT?" 
in Part B of this Prospectus.)

(3)  Each Trust (and therefore Unitholders) will bear all or a portion of its 
estimated organizational costs which will be deferred and amortized over the 
life of the respective Trust.

(4)  Representing, as set forth in "ACCRUED INTEREST" in Part B of this 
Prospectus, advancement by the Trustee of an amount equal to the accrued 
Bonds' interest as of the Initial Date of Deposit.

(5)  Aggregate Public Offering Price (exclusive of accrued interest) computed 
as set forth under "PUBLIC OFFERING PRICE" in Part B of this Prospectus.

(6)  The gross underwriting commission of      % of the Public Offering Price 
has been calculated on the assumption that the Units sold are not subject to 
a reduction of sales charge for quantity purchases.  In single transactions 
involving 500 Units or more, the sales charge is reduced.  (See "PUBLIC 
OFFERING PRICE" in Part B of this Prospectus.)

                               (GENERAL TERMS)

                             _______________, 1997

    This Part B of the Prospectus may not be distributed unless accompanied 
by Part A. Both Parts of this Prospectus should be retained for future 
reference.

    FURTHER DETAIL REGARDING CERTAIN OF THE INFORMATION PROVIDED IN THE 
PROSPECTUS MAY BE OBTAINED WITHIN FIVE BUSINESS DAYS OF WRITTEN OR TELEPHONIC 
REQUEST TO THE TRUSTEE AT 4 NEW YORK PLAZA, NEW YORK, NY 10004-2413 OR (800) 
257-8787.

    CURRENTLY OFFERED AT PUBLIC OFFERING PRICE PLUS INTEREST ACCRUED TO THE 
DATE OF SETTLEMENT.  MINIMUM PURCHASE -- EITHER $5,000 OR 50 UNITS, WHICHEVER 
IS LESS.

THIS NUVEEN UNIT TRUST SERIES consists of the underlying separate unit 
investment trusts set forth in Part A of this Prospectus.  Each Trust 
initially consists of delivery statements relating to contracts to purchase 
Bonds and, thereafter, will consist of a portfolio of investment grade, 
corporate debt obligations issued after July 18, 1984 (see "SCHEDULE OF 
INVESTMENTS" appearing in Part A of this Prospectus).  Except in specific 
instances as noted in Part A of this Prospectus, the information contained in 
this Part B shall apply to the Trust in its entirety.

THE OBJECTIVE of the Trusts is to provide a high level of current income 
through an investment in a portfolio of investment grade, corporate debt 
obligations issued after July 18, 1984.

DISTRIBUTIONS of interest received by a Trust will be made monthly.  (See 
"DISTRIBUTIONS TO UNITHOLDERS.")  Distribution of funds in the Principal 
Account, if any, will ordinarily be made monthly.

FOR ESTIMATED LONG TERM RETURNS AND ESTIMATED CURRENT RETURNS to Unitholders 
on the business day prior to the Initial Date of Deposit, see Part A of this 
Prospectus and "ESTIMATED LONG TERM RETURN AND ESTIMATED CURRENT RETURN."

THE PUBLIC OFFERING PRICE per Unit of each Trust during the initial offering 
period is equal to a pro rata share of the OFFERING  prices of the Bonds in 
such Trust's portfolio plus a sales charge as set forth in Part A of this 
Prospectus  The Secondary Market Public Offering Price per Unit for each 
Trust will be equal to a pro rata share of the sum of BID prices of the Bonds 
in such Trust plus the sales charges as set forth in Part A of this 
Prospectus.  Accrued interest from 

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND 
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES 
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE 
ACCURACY OR ADEQUACY OF THIS PROSPECTUS.  ANY REPRESENTATION TO THE CONTRARY 
IS A CRIMINAL OFFENSE.

<PAGE>

the preceding Record Date to, but not including, the settlement date 
(normally three business days after purchase) is added to the Public Offering 
Price.  The sales charge is reduced on a graduated scale for sales involving 
at least the number of Units set forth in Part A of this Prospectus.

A UNITHOLDER MAY REDEEM UNITS at the office of the Trustee at prices based 
upon the BID prices of the Bonds.  The price received upon redemption may be 
more or less than the amount paid by Unitholders, depending upon the value of 
the Bonds on the date of tender for redemption.  (See "REDEMPTION.")  The 
Sponsor, although not required to do so, intends to make a secondary market 
for the Units of the Trusts at prices based upon the bid prices of the Bonds 
in the respective Trusts.  (See "MARKET FOR UNITS.")

RISK FACTORS.  An investment in a Trust should be made with an understanding 
of the risks associated therewith, including, among other factors, the 
inability of the issuer or an insurer to pay the principal of or interest on 
a bond when due, the general condition of the relevant bond market, economic 
recession, volatile interest rates, early call provisions and changes to the 
tax status of the Bonds.  The value of the underlying Bonds will fluctuate 
inversely with changes in interest rates.  Although in recent years interest 
rates have been relatively stable, the uncertain economic conditions of prior 
years, together with the monetary policies and fiscal measures adopted to 
attempt to deal with them, resulted in wide fluctuations of interest rates 
and, thus, in the value of fixed rate, corporate debt obligations.  The 
Sponsor cannot predict the degree to which such fluctuations will continue in 
the future.  See Part A of this Prospectus and "RISK FACTORS."

NUVEEN UNIT TRUSTS

This Nuveen Unit Trust is one of a series of separate but similar investment 
companies created by the Sponsor, each of which is designated by a different 
Series number.  The underlying unit investment trusts contained in this 
Series are combined under one Trust Indenture and Agreement.  Specific 
information regarding each Trust is set forth in Part A of this Prospectus.  
The various Nuveen Unit Trusts are collectively referred to herein as the 
"TRUSTS."  This Series was created under the laws of the State of New York 
pursuant to a Trust Indenture and Agreement dated the Initial Date of Deposit 
(the "INDENTURE") between John Nuveen & Co. Incorporated ("NUVEEN" or the 
"SPONSOR") and The Chase Manhattan Bank (the "TRUSTEE").

The Sponsor has deposited with the Trustee delivery statements relating to 
contracts for the purchase of fixed rate, corporate debt obligations together 
with funds represented by an irrevocable letter of credit issued by a major 
commercial bank in the amount, including accrued interest, required for their 
purchase (or the obligations themselves) (the "BONDS").  See "SCHEDULE OF 
INVESTMENTS" in Part A of this Prospectus, for a description of the Bonds 
deposited in a Trust.  See "SUMMARY OF PORTFOLIO" and "RISK FACTORS" for a 
discussion of zero coupon bonds and stripped obligations included in the 
Trusts, if any.  Some of the delivery statements may relate to contracts for 
the purchase of "when issued" or other Bonds with delivery dates after the 
date of settlement for a purchase made on the Initial Date of Deposit.  See 
the "SCHEDULE OF INVESTMENTS" in Part A of this Prospectus and "COMPOSITION 
OF TRUSTS."  For a discussion of the Sponsor's obligations in the event of a 
failure of any contract for the purchase of any of the Bonds and its limited 
right to substitute other bonds to replace any failed contract, see 
"COMPOSITION OF TRUSTS."

The Trustee has delivered to the Sponsor registered Units which represent 
ownership of the entire Trust, and which are offered for sale by this 
Prospectus.  Each Unit of a Trust represents a fractional undivided interest 
in the principal and net income of such Trust in the ratio set forth in 
"PERFORMANCE INFORMATION" in Part A of this Prospectus.  Units may only be 
sold in states in which they are registered.  To the extent that any Units of 
any Trust are redeemed by the Trustee, the aggregate value of the Trust's 
assets will decrease by the amount paid to the redeeming Unitholder, but the 
fractional undivided interest of each unredeemed Unit in such Trust will 
increase proportionately.  The Sponsor will initially, and from time to time 
thereafter, hold Units in connection with their offering.

Additional Units of each Trust may be issued from time to time following the 
Initial Date of Deposit by depositing in such Trust additional Bonds or 
contracts for the purchase thereof together with irrevocable letters of 
credit or cash.  As additional Units are issued by a Trust as a result of the 
deposit of additional Bonds by the Sponsor, the aggregate value of the Bonds 
in a Trust will be increased and the fractional undivided interest in such 
Trust represented by each Unit will be decreased.  The Sponsor may continue 
to make additional deposits of Bonds into such Trust following the Initial 
Date of Deposit, provided that such additional deposits will be in principal 

                                      -4-


<PAGE>

amounts which will maintain the same original percentage relationship among 
the principal amounts of the Bonds in such Trust established on the Initial 
Date of Deposit.  Thus, although additional Units will be issued, each Unit 
will continue to represent the same principal amount of each Bond, and the 
percentage relationship among the principal amount of each Bond in the 
respective Trust will remain the same.  To the extent that any Units are 
redeemed by the Trustee or additional Units are issued as a result of 
additional Bonds being deposited by the Sponsor, the fractional undivided 
interest in a Trust represented by each unredeemed Unit will increase or 
decrease accordingly, although the actual interest in such Trust represented 
by such fraction will remain unchanged.  Units will remain outstanding until 
redeemed upon tender to the Trustee by Unitholders, which may include the 
Sponsor, or until termination of the Trust Agreement.

OBJECTIVE OF THE TRUSTS

The objective of the Trusts is designed to provide a high level of current 
income and preservation of capital.  The Trusts may be an appropriate 
investment vehicle for investors who wish to participate in a portfolio of 
taxable fixed income obligations issued by corporate obligors with greater 
diversification than investors might be able to acquire individually.  Bonds 
of the type deposited in the Trusts often are not available in small amounts. 
 Diversification of the Trusts' assets will not eliminate the risk of loss 
always inherent in the ownership of corporate debt obligations.  In addition, 
for certain Unitholders who are not United States citizens or residents, 
interest income will be exempt from withholding for U.S. federal income tax 
purposes, if certain conditions are met.

SUMMARY OF PORTFOLIOS

In selecting Bonds for deposit in the Trusts, the following factors, among 
others, were considered by the Sponsor:  (a) the prices and yields of such 
Bonds relative to other Bonds of similar quality and maturity, including the 
extent to which such Bonds are traded at a premium or discount from par; (b) 
the present rating and credit quality of the issuers of the Bonds and the 
potential improvement in the credit quality of such issuers; (c) the 
diversification of the Bonds as to location of issuer; (d) the income to the 
Unitholders of the Trusts; (e) whether the Bonds were issued after July 18, 
1984; and (f) the stated maturities of the Bonds.

RISK FACTORS

CORPORATE DEBT OBLIGATIONS.  An investment in Units of a Trust should be made 
with an understanding of the risks that an investment in fixed rate, 
investment grade corporate debt obligations may entail, including the risk 
that the value of the Units will decline with increases in interest rates.  
In recent years there have been wide fluctuations in interest rates and thus 
in the value of fixed rate, debt obligations generally.  Generally, bonds 
with longer maturities will fluctuate in value more than bonds with shorter 
maturities.  A slowdown in the economy, or a development adversely affecting 

                                      -5-


<PAGE>

an issuer's creditworthiness, may result in the issuer being unable to 
maintain earnings or sell assets at the rate and at the prices, respectively, 
that are required to produce sufficient cash flow to meet its interest and 
principal requirements.  The Portfolio consists of Bonds that, in many cases, 
do not have the benefit of covenants that would prevent the issuer from 
engaging in capital restructurings or borrowing transactions in connection 
with corporate acquisitions, leveraged buyouts or restructurings that could 
have the effect of reducing the ability of the issuer to meet its obligations 
and might result in the ratings of the Bonds and the value of the underlying 
portfolio being reduced.

Should the issuer of any Bond default in the payment of principal or 
interest, the Trust may incur additional expenses seeking payment on the 
defaulted Bond.  Because amounts (if any) recovered by a Trust in payment 
under the defaulted Bond may not be reflected in the value of the Units until 
actually received by such Trust, and depending upon when a Unitholder 
purchases or sell his or her Units, it is possible that a Unitholder would 
bear a portion of the cost of recovery without receiving any portion of the 
payment recovered.

Certain of the Bonds may have been deposited at a market discount or premium 
principally because their interest rates are lower or higher than prevailing 
rates on comparable bonds.  The current returns of market discount bonds are 
lower than comparably rated bonds selling at par because discount bonds tend 
to increase in market value as they approach maturity.  The current returns 
of market premium bonds are higher than comparably rated bonds selling at par 
because premium bonds tend to decrease in market value as they approach 
maturity.  Because part of the purchase price is returned through current 
income payments and not at maturity, an early redemption at par of a premium 
bond will result in a reduction in yield to a Trust.  Market premium or 
discount attributable to interest rate changes does not indicate market 
confidence or lack of confidence in the issue.

PUBLIC UTILITY ISSUES.  Certain of the Bonds in a Trust may be obligations of 
public utility issuers.  In general, public utilities are regulated 
monopolies engaged in the business of supplying light, water, power, heat, 
transportation or means of communication.  Historically, the utilities 
industry has provided investors in securities issued by companies in this 
industry with high levels of reliability, stability and relative total return 
on their investments.  However, an investment in a Trust which contains 
obligations of public utility issuers should be made with an understanding of 
the characteristics of such issuers and the risks which such an investment 
may entail.  General problems of such issuers would include the difficulty in 
financing large construction programs in an inflationary period, the 
limitations on operations and increased costs and delays attributable to 
environmental considerations, the difficulty of the capital market in 
absorbing utility debt, the difficulty in obtaining fuel at reasonable prices 
and the effect of energy conservation.  All of such issuers have been 
experiencing certain of these problems in varying degrees.  In addition, 
federal, state and municipal governmental authorities may from time to time 
review existing, and impose additional, regulations governing the licensing, 
construction and operation of nuclear power plants, which may adversely 
affect the ability of the issuers of certain of such Bonds in certain Trusts 
to make payments of principal and/or interest on such Bonds.

Utilities are generally subject to extensive regulation by state utility 
commissions which, for example, establish the rates which may be charged and 

                                      -6-


<PAGE>

the appropriate rate of return on an approved asset base, which must be 
approved by the state commissions.  Certain utilities have had difficulty 
from time to time in persuading regulators, who are subject to political 
pressures, to grant rate increases necessary to maintain an adequate return 
on investment and voters in many states have the ability to impose limits on 
rate adjustments (for example, by initiative or referendum).  Any unexpected 
limitations could negatively affect the profitability of utilities whose 
budgets are planned far in advance.  Also, changes in certain accounting 
standards currently under consideration by the Financial Accounting Standards 
Board could cause significant write-downs of assets and reductions in 
earnings for many investor-owned utilities.  In addition, gas pipeline and 
distribution companies have had difficulties in adjusting to short and 
surplus energy supplies, enforcing or being required to comply with long-term 
contracts and avoiding litigation from their customers, on the one hand, or 
suppliers, on the other.

Certain of the issuers of the Bonds in a Trust may own or operate nuclear 
generating facilities.  Governmental authorities may from time to time review 
existing, and impose additional, requirements governing the licensing, 
construction and operation of nuclear power plants.  Nuclear generating 
projects in the electric utility industry have experienced substantial cost 
increases, construction delays and licensing difficulties.  These have been 
caused by various factors, including inflation, high financing costs, 
required design changes and rework, allegedly faulty construction, objections 
by groups and governmental officials, limits on the ability to finance, 
reduced forecasts of energy requirements and economic conditions.  This 
experience indicates that the risk of significant cost increases, delays and 
licensing difficulties remains present through completion and achievement of 
commercial operation of any nuclear project.  Also, nuclear generating units 
in service have experienced unplanned outages or extensions of scheduled 
outages due to equipment problems or new regulatory requirements sometimes 
followed by a significant delay in obtaining regulatory approval to return to 
service.  A major accident at a nuclear plan anywhere, such as the accident 
at a plant in Chernobyl, U.S.S.R., could cause the imposition of limits or 
prohibitions on the operation, construction or licensing of nuclear units in 
the United States.

In view of the uncertainties discussed above, there can be no assurance that 
any bond issuer's share of the full cost of nuclear units under construction 
ultimately will be recovered in rates or of the extent to which a bond issuer 
could earn an adequate return on its investment in such units.  The 
likelihood of a significantly adverse event occurring in any of the areas of 
concern described above varies, as does the potential severity of any adverse 
impact.  It should be recognized, however, that one or more of such adverse 
events could occur and individually or collectively could have a material 
adverse impact on the financial condition or the results of operations or on 
a bond issuer's ability to make interest and principal payments on its 
outstanding debt.

Other general problems of the gas, water, telephone and electric utility 
industry (including state and local joint action power agencies) include 
difficulty in obtaining timely and adequate rate increases, difficulty in 
financing large construction programs to provide new or replacement 
facilities during an inflationary period, rising costs of rail transportation 
to transport fossil fuels, the uncertainty of transmission service costs for 
both interstate and intrastate transactions, changes in tax laws which 

                                      -7-


<PAGE>

adversely affect a utility's ability to operate profitably, increased 
competition in service costs, reductions in estimates of future demand for 
electricity and gas in certain areas of the country, restrictions on 
operations and increased cost and delays attributable to environmental 
considerations, uncertain availability and increased cost of capital, 
unavailability of fuel for electric generation at reasonable prices, 
including the steady rise in fuel costs and the costs associated with 
conversion to alternate fuel sources such as coal, availability and cost of 
natural gas for resale, technical and cost factors and other problems 
associated with construction, licensing, regulation and operation of nuclear 
facilities for electric generation, including among other considerations the 
problems associated with the use of radioactive materials and the disposal of 
radioactive wastes, and the effects of energy conservation.  Each of the 
problems referred to could adversely affect the ability of the issuer of any 
utility Bonds in a Trust to make payments due on these Bonds.

In addition, the ability of state and local joint action power agencies to 
make payments on bonds they have issued is dependent in large part on 
payments made to them pursuant to power supply or similar agreements.

Courts in Washington and Idaho have held that certain agreements between 
Washington Public Power Supply System ("WPPSS") and the WPPSS participants 
are unenforceable because the participants did not have the authority to 
enter into the agreements.  While these decisions are not specifically 
applicable to agreements entered into by public entities in other states, 
they may cause a reexamination of the legal structure and economic viability 
of certain projects financed by joint action power agencies, which might 
exacerbate some of the problems referred to above and possibly lead to legal 
proceedings questioning the enforceability of agreements upon which payment 
of these bonds may depend.

Business conditions of the telephone industry in general may affect the 
performance of a Trust.  General problems of telephone companies include 
regulation of rates for service by the FCC and various state or other 
regulatory agencies.  However, over the last several years regulation has 
been changing, resulting in increased competition.  The new approach is more 
market oriented, more flexible and more complicated.  For example, Federal 
and certain state regulators have instituted "price cap" regulation which 
couples protection of rate payers for basic services with flexible pricing 
for ancillary services.  These new approaches to regulation could lead to 
greater risks as well as greater rewards for operating telephone companies 
such as those in the Trusts.  Inflation has substantially increased the 
operating expenses and cost of plant required for growth, service, 
improvement and replacement of existing plant.  Continuing cost increases, to 
the extent not offset by improved productivity and revenues from increased 
business, would result in a decrease in rate of return and a continuing need 
for rate increases.  Although allowances are generally made in rate making 
proceedings for cost increases, delays may be experienced in obtaining the 
necessary rate increases and there can be no assurance that the regulatory 
agencies will grant rate increases adequate to cover operating and other 
expenses and debt service requirements.  To meet increasing competition, 
telephone companies will have to commit substantial capital, technological 
and marketing resources.  Telephone usage, and therefore revenues, could also 

                                      -8-


<PAGE>

be adversely affected by any sustained economic recession.  New technology, 
such as cellular service and fiber optics, will require additional capital 
outlays.  The uncertain outcomes of future labor agreements may also have a 
negative impact on the telephone companies.  Each of these problems could 
adversely affect the ability of the telephone company issuers of any Bonds in 
a portfolio to make payments of principal and interest on their Bonds.

COMPOSITION OF TRUSTS

Each Trust initially consists of delivery statements relating to contracts to 
purchase Bonds (or of such Bonds) as are listed under "SCHEDULE OF 
INVESTMENTS" in Part A of this Prospectus and, thereafter, of such Bonds as 
may continue to be held from time to time (including certain bonds deposited 
in the Trust to create additional Units, in substitution for Bonds not 
delivered to a Trust or in exchange or substitution for Bonds upon certain 
refundings), together with accrued and undistributed interest thereon and 
undistributed cash realized from the disposition of Bonds.

"WHEN-ISSUED" AND "DELAYED DELIVERY" TRANSACTIONS.  The contracts to purchase 
Bonds delivered to the Trustee represent an obligation by issuers or dealers 
to deliver Bonds to the Sponsor for deposit in the Trusts.  Certain of the 
contracts relate to Bonds which have not been issued as of the Initial Date 
of Deposit and which are commonly referred to as "when issued" or "when, as 
and if issued" Bonds.  Although the Sponsor believes it unlikely, if such 
Bonds, or replacement bonds described below, are not acquired by a Trust or 
if their delivery is delayed, the Estimated Current Returns and Estimated 
Long Term Returns shown in Part A of this Prospectus may be reduced.  Certain 
of the contracts for the purchase of Bonds provide for delivery dates after 
the date of settlement for purchases made on the Initial Date of Deposit.  
Interest on such "when issued" and "delayed delivery" Bonds accrues to the 
benefit of Unitholders commencing with the first settlement date for the 
Units.  However, in the opinion of counsel, Unitholders who purchase their 
Units prior to the date such Bonds are actually delivered to the Trustee must 
reduce the tax basis of their Units for interest accruing on such Bonds 
during the interval between their purchase of Units and the delivery of the 
Bonds because such amounts constitute a return of principal.  As a result of 
such adjustment, the Estimated Current Returns set forth in Part A of this 
Prospectus (which are based on the Public Offering Price as of the business 
day prior to the Initial Date of Deposit) may be slightly lower than that 
which Unitholders will receive after the first year, assuming the Portfolio 
does not change and estimated annual expense does not vary from that set 
forth under "PERFORMANCE INFORMATION" in Part A of this Prospectus.  Those 
Bonds in each Trust purchased with delivery dates after the date of 
settlement for purchases made on the Initial Date of Deposit are so noted in 
the "SCHEDULE OF INVESTMENTS" in Part A of this Prospectus.

LIMITED REPLACEMENT OF CERTAIN BONDS.  Neither the Sponsor nor the Trustee 
shall be liable in any way for any default, failure or defect in any Bond.  
In the event of a failure to deliver any Bond that has been purchased for a 
Trust under a contract, including those Bonds purchased on a when, as and if 
issued basis ("FAILED BONDS"), the Sponsor is authorized under the Indenture 
to direct the Trustee to acquire other specified Bonds ("REPLACEMENT BONDS") 
to make up the original corpus of the Trust within 20 days after delivery of 
notice of the failed contract and the cost to the Trust (exclusive of accrued 
interest) may not exceed the amount of funds reserved for the purchase of the 

                                     -9-


<PAGE>

Failed Bonds.  The Replacement Bonds must satisfy the criteria previously 
described for the Trusts and shall be substantially identical to the Failed 
Bonds they replace.  The Replacement Bonds (i) must be payable in United 
States currency, (ii) must be purchased at a price that results in a yield to 
maturity and a current return at least equal to that of the Failed Bonds as 
of the Initial Date of Deposit, (iii) must satisfy any rating criteria for 
Bonds originally included in the Trust, (iv) must be insured prior to 
acquisition by the Trust, (v) must be corporate bonds, debentures, notes or 
other straight debt obligations (whether secured or unsecured and whether 
senior or subordinated) without equity or other conversion features, with 
fixed maturity dates substantially the same as those or the Failed Bonds 
having no warrants or subscription privileges attached and (vi) be issued 
after July 18, 1984.  In addition, Replacement Bonds shall not be "when, as 
and if issued" Bonds.  Whenever a Replacement Bond has been acquired for a 
Trust, the Trustee shall, within five days after the delivery thereof, mail 
or deliver a notice of such acquisition to all Unitholders of the Trust 
involved.  Once the original corpus of the Trust is acquired, the Trustee 
will have no power to vary the investment of the Trust.

To the extent Replacement Bonds are not acquired, the Sponsor shall refund to 
all Unitholders of the Trust involved the sales charge attributable to such 
Failed Bonds not replaced, and the principal and accrued interest 
attributable to such Bonds shall be distributed not more than 30 days after 
the determination of such failure or at such earlier time as the Trustee in 
its sole discretion deems to be in the interest of the Unitholders.  Any such 
accrued interest paid to Unitholders will be paid by the Sponsor.  In the 
event Failed Bonds in a Trust could not be replaced, the Net Annual Interest 
Income per Unit for such Trust would be reduced and the Estimated Current 
Return thereon might be lowered.

SALE, MATURITY AND REDEMPTION OF BONDS.  Certain of the Bonds may from time 
to time under certain circumstances be sold or will mature in accordance with 
their terms.  The proceeds from such events will be used to pay for Units 
redeemed or distributed to Unitholders and not reinvested; accordingly, no 
assurance can be given that a Trust will retain for any length of time its 
present size and composition.

LITIGATION.  To the best knowledge of the Sponsor, there is no litigation 
pending as of the Initial Date of Deposit in respect of any Bonds which might 
reasonably be expected to have a material adverse effect on the Trusts.  It 
is possible that after the Initial Date of Deposit, litigation may be 
initiated with respect to Bonds in any Trust.  The Sponsor is unable to 
predict whether any such litigation may be instituted, or if instituted, 
whether such litigation might have a material adverse effect on the Trusts.

INSURANCE ON THE BONDS

All Bonds in an insured portfolio except for any U.S. Treasury obligations 
are insured as to the scheduled payment of interest and principal either by 
the issuer of the Bonds or by the Sponsor under a financial guaranty 
insurance policy obtained from MBIA Insurance Corporation ("MBIA").  The 
premium for each such insurance policy has been paid in advance by such 

                                     -10-


<PAGE>

issuer or the Sponsor and each such policy is non-cancellable and will remain 
in force so long as the Bonds are outstanding and MBIA remains in business.  
No premiums for such insurance are paid by any Trust.  If MBIA is unable to 
meet its obligations under its policy or if the rating assigned to the 
claims-paying ability of MBIA deteriorates, no other insurer has any 
obligation to insure any issue adversely affected by either of these events.

The aforementioned insurance guarantees the scheduled payment of principal 
and interest on all of the Bonds in an Insured Utility Portfolio except for 
any U.S. Treasury obligations.  It does not guarantee the market value of the 
Bonds or the value of the Units of a Trust.  This insurance is effective so 
long as the Bond is outstanding, whether or not held by a Trust.  Therefore, 
any such insurance may be considered to represent an element of market value 
in regard to the Bonds, but the exact effect, if any, of this insurance on 
such market value cannot be predicted.

MBIA, formerly known as Municipal Bond Investors Insurance Corporation, is 
the principal operating subsidiary of MBIA, Inc., a New York Stock Exchange 
listed company.  MBIA, Inc. is not obligated to pay the debts of or claims 
against MBIA.  MBIA is domiciled in the State of New York and licensed to do 
business in all 50 states, the District of Columbia, the Commonwealth of 
Puerto Rico, the Commonwealth of the Northern Mariana Islands, the Virgin 
Islands of the United States and the Territory of Guam.  MBIA has one 
European branch in the Republic of France.

As of December 31, 1995, MBIA had admitted assets of $3.8 billion (audited), 
total liabilities of $2.5 billion (audited), and total capital and surplus of 
$1.3 billion (audited) determined in accordance with statutory accounting 
practices prescribed or permitted by insurance regulatory authorities.  As of 
March 31, 1996, MBIA had admitted assets of $4.0 billion (unaudited), total 
liabilities of $2.7 billion (unaudited), and total capital and surplus of 
$1.3 billion (unaudited) determined in accordance with statutory accounting 
practices prescribed or permitted by insurance regulatory authorities.  
Copies of MBIA Corporation's financial statements prepared in accordance with 
statutory accounting practices are available from MBIA Corporation.  The 
address of MBIA Corporation is 113 King Street, Armonk, New York 10504.

Moody's rates all bond issues insured by MBIA "Aaa" and short term loans "MIG 
1," both designated to be of the highest quality.  Standard & Poor's, upon 
request, rates all new issues insured by MBIA "AAA."

Because the Bonds in a Trust (other than U.S. Treasury Obligations) are 
insured as to the scheduled payment of principal and interest and on the 
basis of the financial condition and the method of operation of MBIA, 
Standard & Poor's has assigned to Units in an such Trusts its "AAA" 
investment rating.  This is the highest rating assigned to securities by such 
rating agency.  These ratings should not be construed as an approval of the 
offering of the Units by Standard & Poor's or as a guarantee of the market 
value of a Trust or the Units thereof.

                                     -11-


<PAGE>

Bonds in a Trust for which insurance has been obtained by the issuer thereof 
or by the Sponsor from MBIA (all of which were rated "Aaa" by Moody's) may or 
may not have a higher yield than uninsured bonds rated "Aaa" by Moody's.  In 
selecting Bonds for the portfolio of a Trust, the Sponsor has applied the 
criteria hereinbefore described.

PUBLIC OFFERING PRICE

The Public Offering Price of the Units of each Trust is equal to the 
Trustee's determination of the aggregate offering prices of the Bonds 
deposited therein (minus any advancement to the principal account of the 
Trust made by the Trustee) plus a sales charge as set forth in Part A of this 
Prospectus, in each case adding to the total thereof, the cash held by the 
Trust, if any, and dividing the sum so obtained by the number of Units 
outstanding in the Trust.  See "UNIT VALUE AND EVALUATION."

The sales charge applicable to quantity purchases is reduced on a graduated 
scale as set forth in Part A of this Prospectus.  For purposes of calculating 
the applicable sales charge, purchasers who have indicated their intent to 
purchase a specified amount of Units of any Trust in the primary or secondary 
offering period by executing and delivering a letter of intent to the 
Sponsor, which letter of intent must be in a form acceptable to the Sponsor 
and shall have a maximum duration of thirteen months, will be eligible to 
receive a reduced sales charge according to the following tables based on the 
amount of intended aggregate purchases as expressed in the letter of intent.  
Due to administrative limitations and in order to permit adequate tracking, 
the only secondary market purchases that will be permitted to be applied 
toward the intended specified amount and that will receive the corresponding 
reduced sales charge are those Units that are acquired through or from the 
Sponsor.  By establishing a letter of intent, a Unitholder agrees that the 
first purchase of Units following the execution of such letter of intent will 
be at least 5% of the total amount of the intended aggregate purchases 
expressed in such Unitholder's letter of intent.  Further, through the 
establishment of the letter of intent, such Unitholder agrees that Units 
representing 5% of the total amount of the intended purchases will be held in 
escrow by the Trustee pending completion of these purchases.  All 
distributions on Units held in escrow will be credited to such Unitholder's 
account.  If total purchases prior to the expiration of the letter of intent 
period equal or exceed the amount specified in a Unitholder's letter of 
intent, the Units held in escrow will be transferred to such Unitholder's 
account.  A Unitholder who purchases Units during the letter of intent period 
in excess of the number of Units specified in a Unitholder's letter of 
intent, the amount of which would cause the Unitholder to be eligible to 
receive an additional sales charge reduction, will be allowed such additional 
sales charge reduction on the purchase of Units which caused the Unitholder 
to reach such new breakpoint level and on all additional purchases of Units 
during the letter of intent period.  If the total purchases are less than the 
amount specified, the Unitholder involved must pay the Sponsor an amount 
equal to the difference between the amounts paid for these purchases and the 
amounts which would have been paid if the higher sales charge had been 
applied; the Unitholder will, however, be entitled to any reduced sales 
charge qualified for by reaching any lower breakpoint level.  If such 
Unitholder does not pay the additional amount within 20 days after written 
request by the Sponsor or the Unitholder's representative, the Sponsor will 
instruct the Trustee to redeem an appropriate number of the escrowed Units to 

                                     -12-


<PAGE>

meet the required payment.  By establishing a letter of intent, a Unitholder 
irrevocably appoints the Sponsor as attorney to give instructions to redeem 
any or all of such Unitholder's escrowed Units, with full power of 
substitution in the premises.  A Unitholder or his bonds representative must 
notify the Sponsor whenever such Unitholder makes a purchase of Units that he 
wishes to be counted towards the intended amount.

For "secondary market" sales, the Public Offering Price per Unit of each 
Trust is determined by adding to the Trustee's determination of the bid price 
of each Bond in the Trust a sales charge  as set forth in Part A of this 
Prospectus.  See "UNIT VALUE AND EVALUATION."  The secondary market sales 
charge is reduced with respect to quantity purchases in such amounts as set 
forth in Part A of this Prospectus.

Pursuant to the terms of the Indenture, the Trustee may terminate a Trust if 
the net asset value of such Trust, as shown by any evaluation, is less than 
20% of the original principal amount of the Trust.

At all times while Units are being offered for sale, the Sponsor will 
appraise or cause to be appraised daily the value of the underlying Bonds in 
each Trust as of 4:00 p.m. eastern time, or as of any earlier closing time on 
a day on which the New York Stock Exchange (the "EXCHANGE") is scheduled in 
advance to close at such earlier time and will adjust the Public Offering 
Price of the Units commensurate with such appraisal.  Such Public Offering 
Price will be effective for all orders received by a dealer or the Sponsor at 
or prior to 4:00 p.m. eastern time on each such day or as of any earlier 
closing time on a day on which the Exchange is scheduled in advance to close 
at such earlier time.  Orders received after that time, or on a day when the 
Exchange is closed for a scheduled holiday or weekend, will be held until the 
next determination of price.

Accrued interest from the preceding Record Date to, but not including, the 
settlement date of the transaction (three business days after purchase) will 
be added to the Public Offering Price to determine the purchase price of 
Units.  See "ACCRUED INTEREST."

The graduated sales charges set forth above will apply on all applicable 
purchases of Nuveen investment company securities on any one day by the same 
purchaser in the amounts stated, and for this purpose purchases of this 
Series will be aggregated with concurrent purchases of any other Series or of 
shares of any open-end management investment company of which the Sponsor is 
principal underwriter and with respect to the purchase of which a sales 
charge is imposed.  Purchases by or for the account of an individual and his 
or her spouse and children under 21 years of age ("IMMEDIATE FAMILY MEMBERS") 
will be aggregated to determine the applicable sales charge.  The graduated 
sales charges are also applicable to a trustee or other fiduciary purchasing 
securities for a single trust estate or single fiduciary account.  Units may 
be purchased at the Public Offering Price without a sales charge by officers 
or directors and by bona fide, full-time employees of Nuveen, Nuveen Advisory 
Corp., Nuveen Institutional Advisory Corp. and The John Nuveen Company, 
including in each case these individuals and their immediate family members 
(as defined above).

                                     -13-


<PAGE>

Units may be purchased in the primary market with a sales charge of _____% of 
the Public Offering Price by (1) investors who purchase Units through 
registered investment advisers, certified financial planners and registered 
broker-dealers who in each case either charge periodic fees for financial 
planning, investment advisory or asset management services, or provide such 
services in connection with the establishment of an investment account for 
which a comprehensive "wrap fee" charge is imposed, (2) bank trust 
departments investing funds over which they exercise exclusive discretionary 
investment authority and that are held in a fiduciary, agency, custodial or 
similar capacity, (3) any person who for at least 90 days, has been an 
officer, director or bona fide employee of any firm offering Units for sale 
to investors or their immediate family members (as defined above) and (4) 
officers and directors of bank holding companies that make Units available 
directly or through subsidiaries or bank affiliates (collectively, the 
"DISCOUNTED PURCHASES").  In addition, such investors may purchase Units in 
the secondary market at the Public Offering Price for non-breakpoint 
purchases minus the concession the Sponsor typically allows to brokers and 
dealers for non-breakpoint purchases.  Notwithstanding anything to the 
contrary in this Prospectus, investors who purchase Units as described in 
this paragraph will not receive sales charge reductions for quantity 
purchases.

The initial or primary Public Offering Price of the Units in each Trust is 
based upon a pro rata share of the offering prices per Unit of the Bonds in 
such Trust plus the applicable sales charge.  The secondary market Public 
Offering Price of each Trust is based upon a pro rata share of the bid prices 
per Unit of the Bonds in such Trust plus the applicable sales charge.  The 
offering prices of Bonds in a Trust may be expected to average between 1/2% 
to 2% more than the bid prices of such Bonds.  The difference between the bid 
side evaluation and the offering side evaluation of the Bonds in each Trust 
on the business day prior to the Initial Date of Deposit is shown in the 
discussion of each Trust portfolio.

Whether or not Units are being offered for sale, the Sponsor will determine 
the aggregate value of each Trust as of 4:00 p.m. eastern time:  (i) on each 
June 30 or December 31 (or, if such date is not a business day, the last 
business day prior thereto), (ii) on any day on which a Unit is tendered for 
redemption (or the next succeeding business day if the date of tender is a 
non-business day) and (iii) at such other times as may be necessary.  For 
this purpose, a "business day" shall be any day on which the Exchange is 
normally open.  (See "UNIT VALUE AND EVALUATION.")

MARKET FOR UNITS

During the initial public offering period, the Sponsor intends to offer to 
purchase Units of each Trust at a price equivalent to the pro rata share per 
Unit of the offering prices of the Bonds in such Trust (plus accrued 
interest).  Afterward, although it is not obligated to do so, the Sponsor 
intends to maintain a secondary market for Units of each Trust at its own 
expense and continuously to offer to purchase Units of each Trust at prices, 
subject to change at any time, which are based upon the bid prices of Bonds 
in the respective portfolios of the Trusts.  UNITHOLDERS WHO WISH TO DISPOSE 
OF THEIR UNITS SHOULD INQUIRE OF THE TRUSTEE OR THEIR BROKER AS TO THE 
CURRENT REDEMPTION PRICE.  (See "REDEMPTION.")  In connection with its 
secondary market making activities, the Sponsor may from time to time enter 

                                     -14-


<PAGE>

into secondary market joint account agreements with other brokers and 
dealers.  Pursuant to such an agreement, the Sponsor will purchase Units from 
the broker or dealer at the bid price and will place the Units into a joint 
account managed by the Sponsor; sales from the account will be made in 
accordance with the then current prospectus and the Sponsor and the broker or 
dealer will share profits and losses in the joint account in accordance with 
the terms of their joint account agreement.

Certificates, if any, for Units are delivered to the purchaser as promptly 
after the date of settlement (three business days after purchase) as the 
Trustee can complete the mechanics of registration, normally within 48 hours 
after registration instructions are received.  Purchasers of Units to whom 
Certificates are issued will be unable to exercise any right of redemption 
until they have received their Certificates, properly endorsed for transfer.  
(See "REDEMPTION.")

ACCRUED INTEREST

Accrued interest is the accumulation of unpaid interest on a bond from the 
last day on which interest thereon was paid.  Interest on Bonds in each Trust 
is accounted for daily on an accrual basis.  For this reason, the purchase 
price of Units of a Trust will include not only the Public Offering Price but 
also the proportionate share of accrued interest to the date of settlement.  
Unitholders will receive on the next distribution date of a Trust the amount, 
if any, of accrued interest paid on their Units.

In an effort to reduce the amount of accrued interest that investors would 
have to pay in addition to the Public Offering Price, the Trustee has agreed 
to advance to each Trust the amount of accrued interest due on the Bonds as 
of the Initial Date of Deposit (which has been designated the first Record 
Date).  This accrued interest will be paid to the Sponsor as the holder of 
record of all Units on the Initial Date of Deposit.  Consequently, the amount 
of accrued interest to be added to the Public Offering Price of Units will 
include only accrued interest from the Initial Date of Deposit to, but not 
including, the date of settlement of the investor's purchase (three business 
days after purchase), less any distributions from the related Interest 
Account.  The Trustee will recover its advancements (without interest or 
other cost to the Trusts) from interest received on the Bonds deposited in 
each Trust.

The Trustee has no cash for distribution to Unitholders until it receives 
interest payments on the Bonds in the Trusts.  Since interest is accrued 
daily but paid only semi-annually, during the initial months of the Trusts, 
the Interest Accounts, consisting of accrued but uncollected interest and 
collected interest (cash), will be predominantly the uncollected accrued 
interest that is not available for distribution.  However, due to advances by 
the Trustee, the Trustee will provide a first distribution approximately 30 
days after the Initial Date of Deposit.  Assuming each Trust retains its 
original size and composition and expenses and fees remain the same, annual 
interest collected and distributed will approximate the estimated Net Annual 
Interest Income stated in Part A of this Prospectus.  However, the amount of 
accrued interest at any point in time will be greater than the amount that 

                                     -15-


<PAGE>

the Trustee will have actually received and distributed to the Unitholders.  
Therefore, there will always remain an item of accrued interest that is 
included in the purchase price and the redemption price of the Units.

Interest is accounted for daily and a proportionate share of accrued and 
undistributed interest computed from the preceding Record Date is added to 
the daily valuation of each Unit of each Trust.  (See Part A of this 
Prospectus and "WHEN ARE DISTRIBUTIONS MADE TO UNITHOLDERS?")  As Bonds 
mature, or are redeemed or sold, the accrued interest applicable to such 
bonds is collected and subsequently distributed to Unitholders.  Unitholders 
who sell or redeem all or a portion of their Units will be paid their 
proportionate share of the remaining accrued interest to, but not including, 
the third business day following the date of sale or tender.

ESTIMATED LONG TERM RETURN AND ESTIMATED CURRENT RETURN

The Estimated Long Term Return for each Trust is a measure of the return to 
the investor expected to be earned over the estimated life of the Trust.  The 
Estimated Long Term Return represents an average of the yields to maturity 
(or call) of the Bonds in the Trust's portfolio calculated in accordance with 
accepted bond practice and adjusted to reflect expenses and sales charges.  
Under accepted bond practice, bonds are customarily offered to investors on a 
"yield price" basis, which involves computation of yield to maturity or to an 
earlier call date (whichever produces the lower yield), and which takes into 
account not only the interest payable on the bonds but also the amortization 
or accretion of any premium over, or discount from, the par (maturity) value 
inherent in the bond's purchase price.  In the calculation of Estimated Long 
Term Return, the average yield for a Trust's portfolio is derived by 
weighting each Bond's yield by the market value of the Bond and by the amount 
of time remaining to the date to which the Bond is priced.  This weighted 
average yield is then adjusted to reflect estimated expenses, is compounded, 
and is reduced by a factor which represents the amortization of the sales 
charge over the expected average life of a Trust.  The Estimated Long Term 
Return calculation does not take into account the effect of a first 
distribution which may be less than a regular distribution or may be paid at 
some point after 30 days.

Estimated Current Return is computed by dividing the Net Annual Interest 
Income per Unit by the Public Offering Price.  In contrast to Estimated Long 
Term Return, Estimated Current Return does not reflect the amortization of 
premium or accretion of discount, if any, on the Bonds in a Trust's 
portfolio.  Net Annual Interest Income per Unit is calculated by dividing the 
annual interest income to a Trust, less estimated expenses, by the number of 
Units outstanding.

Net Annual Interest Income per Unit, used to calculate Estimated Current 
Return, will vary with changes in fees and expenses of the Trustee and the 
Evaluator and with the redemption, maturity, exchange or sale of Bonds.  A 
Unitholder's actual return may vary significantly from the Estimated 
Long-Term Return, based on their holding period, market interest rate 
changes, other factors affecting the prices of individual bonds in the 
portfolio, and differences between the expected remaining life of portfolio 

                                     -16-


<PAGE>

bonds and the actual length of time that they remain in a Trust; such actual 
holding periods may be reduced by termination of a Trust, as described in 
"OTHER INFORMATION."  Since both the Estimated Current Return and the 
Estimated Long Term Return quoted herein are based on the market value of the 
underlying Bonds on the business day prior to the Initial Date of Deposit, 
subsequent calculations of these performance measures will reflect the then 
current market value of the underlying Bonds and may be higher or lower.  The 
Sponsor will provide estimated cash flow information relating to a Trust 
without charge to each potential investor in a Trust who receives this 
prospectus and makes an oral or written request to the Sponsor for such 
information.

A portion of the monies received by a Trust may be treated, in the first year 
only, as a return of principal due to the inclusion in the Trust portfolio of 
"when-issued" or other Bonds having delivery dates after the date of 
settlement for purchases made on the Initial Date of Deposit.  A consequence 
of this treatment is that in the computation of Estimated Current Return for 
the first year, such monies are excluded from Net Annual Interest Income and 
treated as an adjustment to the Public Offering Price.  (See "Performance 
Information" appearing in Part A of this Prospectus, "COMPOSITION OF TRUSTS" 
and "WHAT IS THE TAX STATUS OF UNITHOLDERS?")

A comparison of estimated current returns with the returns on various other 
taxable investments is one element to consider in making an investment 
decision.  The Sponsor may from time to time in its advertising and sales 
materials compare the then current estimated returns on a Trust and returns 
over specified periods on other similar Nuveen Trusts with returns on taxable 
investments such as corporate or U.S. Government bonds, bank CD's and money 
market accounts or money market funds, each of which has investment 
characteristics that may differ from those of the Trust.  U.S. Government 
bonds, for example, are backed by the full faith and credit of the U.S. 
Government and bank CD's and money market accounts are insured by an agency 
of the federal government.  Money market accounts and money market funds 
provide stability of principal, but pay interest at rates that vary with the 
condition of the short-term debt market.  The investment characteristics of 
the Trusts are described more fully elsewhere in the Prospectus.

EVALUATION OF BONDS AT THE INITIAL DATE OF DEPOSIT

The prices at which the Bonds deposited in the Trusts would have been offered 
to the public on the business day prior to the Initial Date of Deposit were 
determined by the Trustee on the basis of an evaluation of such bonds 
prepared by Kenny S&P Evaluation Services, a division of J. J. Kenny Co., 
Inc. ("KENNY S&P"), a firm regularly engaged in the business of evaluating, 
quoting or appraising comparable bonds.

The amount by which the Trustee's determination of the OFFERING PRICES of the 
Bonds deposited in the Trust was greater or less than the cost of such Bonds 
to the Sponsor was PROFIT OR LOSS to the Sponsor exclusive of any 
underwriting profit.  (See Part A of this Prospectus.)  The Sponsor also may 
realize FURTHER PROFIT OR SUSTAIN FURTHER LOSS as a result of fluctuations in 
the Public Offering Price of the Units.  Cash, if any, made available to the

Sponsor prior to the settlement date for a purchase of Units, or prior to the 
acquisition of all Portfolio bonds by a Trust, may be available for use in 
the Sponsor's business, and may be of benefit to the Sponsor.

TAX STATUS

In the Opinion of Chapman and Cutler, special counsel for the Sponsor, under 
existing law:

  1.  Each Trust is not an association taxable as a corporation for federal 
income tax purposes.

  2.  Each Unitholder will be considered the owner of a pro rata portion of 
each of the Trust assets for federal income tax purposes under Subpart E, 
Subchapter J of Chapter 1 of the Internal Revenue Code of 1986, as amended 
(the "CODE").  Each Unitholder will be considered to have received his pro 
rata share of income derived from each Trust asset when such income is 
considered to be received by a Trust.

  3.  Each Unitholder will have a taxable event when a Bond is disposed of 
(whether by sale, exchange, liquidation, redemption, or payment at maturity) 
or when the Unitholder redeems or sells his Units.  The cost of the Units to 
a Unitholder on the date such Units are purchased is allocated among the 
Bonds held in a Trust (in accordance with the proportion of the fair market 
values of such Bonds) in order to determine his tax basis for his pro rata 
portion in each Bond.  Unitholders must reduce the tax basis of their Units 
for their share of accrued interest received, if any, on Bonds delivered 
after the date on which the Unitholders pay for their Units and, 
consequently, such Unitholders may have an increase in taxable gain or 
reduction in capital loss upon the disposition of such Units.  Gain or loss 
upon the sale or redemption of Units is measured by comparing the proceeds of 
such sale or redemption with the adjusted basis of the Units.  If the Trustee 
disposes of Bonds, gain or loss is recognized to the Unitholder (subject to 
various non-recognition provisions of the Code).  The amount of any such gain 
or loss is measured by comparing the Unitholders' pro rata share of the total 
proceeds from such disposition with his basis for his fractional interest in 
the asset disposed of.  The basis of each Unit and of each Bond which was 
issued with original issue discount must be increased by the amount of 
accrued original issue discount and the basis of each Unit and of each Bond 
which was purchased by a Trust at a premium must be reduced by the annual 
amortization of bond premium which the Unitholder has properly elected to 
amortize under Section 171 of the Code.  The tax basis reduction requirements 
of the Code relating to amortization of bond premium may, under some 
circumstances, result in the Unitholder realizing a taxable gain when his 
Units are sold or redeemed for an amount equal to or less than his original 

                                     -18-

cost.  A Trust may contain certain "zero coupon" Securities (the "STRIPPED 
TREASURY SECURITIES") that are treated as bonds that were originally issued 
at an original issue discount provided, pursuant to a Treasury Regulation 
(the "REGULATION") issued on December 28, 1992, that the amount of original 
issue discount determined under Section 1286 of the Code is not less than a 
DE MINIMIS amount as determined thereunder.  Because the Stripped Treasury 
Securities represent interests in "stripped" U.S. Treasury bonds, a 
Unitholder's initial cost for his pro rata portion of each Stripped Treasury 
Security held by a Trust (determined at the time he acquires his Units, in 
the manner described above) shall be treated as its "purchase price" by the 
Unitholder.  Original issue discount is effectively treated as interest for 
federal income tax purposes, and the amount of original issue discount in 
this case is generally the difference between the bond's purchase price and 
its stated redemption price at maturity.  A Unitholder will be required to 
include in gross income for each taxable year the sum of his daily portions 
of original issue discount attributable to the Stripped Treasury Securities 
held by a Trust as such original issue discount accrues and will, in general, 
be subject to federal income tax with respect to the total amount of such 
original issue discount that accrues for such year even though the income is 
not distributed to the Unitholders during such year to the extent it is not 
less than a DE MINIMIS amount as determined under the Regulation.  To the 
extent that the amount of such discount is less than the respective DE 
MINIMIS amount, such discount shall be treated as zero.  In general, original 
issue discount accrues daily under a constant interest rate method which 
takes into account the semi-annual compounding of accrued interest.  In the 
case of the Stripped Treasury Securities, this method will generally result 
in an increasing amount of income to the Unitholders each year.

Limitations on Deductibility of Trust Expenses by Unitholders -- Each 
Unitholder's pro rata share of each expense paid by a Trust is deductible by 
the Unitholder to the same extent as though the expense had been paid 
directly by him.  It should be noted that as a result of the Tax Reform Act 
of 1986, certain miscellaneous itemized deductions, such as investment 
expenses, tax return preparation fees and employee business expenses, may be 
deductible by an individual only to the extent they exceed 2% of such 
individual's adjusted gross income.  Unitholders may be required to treat 
certain expenses of a Trust as miscellaneous itemized deductions subject to 
this limitation.

Premium--If a Unitholder's tax basis of his pro rata portion in any Bonds 
held by a Trust exceeds the amount payable by the issuer of the Bond with 
respect to such pro rata interest upon the maturity of the Bond, such excess 
would be considered "premium" which may be amortized by the Unitholder at the 
Unitholder's election as provided in Section 171 of the Code.

Original Issue Discount--Certain of the Bonds in a Trust may have been 
acquired with "original issue discount."  In the case of any Bonds in a Trust 
acquired with "original issue discount" that exceeds a "DE MINIMIS" amount as 
specified in the Code, such discount is includable in taxable income of the 
Unitholders on an accrual basis computed daily, without regard to when 
payments of interest on such Bonds are received.  The Code provides a complex 
set of rules regarding the accrual of original issue discount.  These rules 
provide that original issue discount generally accrues on the basis of a 
constant compound interest rate over the term of the Bonds.  Unitholders 
should consult their tax advisers as to the amount of original issue discount 
as it accrues.

                                     -19-


<PAGE>

Special original issue discount rules apply if the purchase price of the Bond 
by a Trust exceeds its original issue price plus the amount of original issue 
discount which would have previously accrued based upon its issue price (its 
"ADJUSTED ISSUE PRICE").  Similarly, these special rules would apply to a 
Unitholder if the tax basis of his pro rata portion of a Security issued with 
original issue discount exceeds his pro rata portion of its adjusted issue 
price.  Unitholders should also consult their tax advisers regarding these 
special rules.

Market Discount -- If a Unitholder's tax basis in his pro rata portion of 
Bonds is less than the allocable portion of such Bond's stated redemption 
price at maturity (or, if issued with original issue discount, the allocable 
portion of its "REVISED ISSUE PRICE"), such difference will constitute market 
discount unless the amount of market discount is "DE MINIMIS" as specified in 
the Code.  Market discount accrues daily computed on a straight-line basis, 
unless the Unitholder elects to calculate accrued market discount under a 
constant-yield method.  The market discount rules do not apply to Stripped 
Treasury Securities because they are stripped debt instruments subject to 
special original issue discount rules discussed above.  Unitholders should 
consult their own tax advisers regarding whether an election should be made 
and as to the amount of market discount which accrues.

Accrued market discount is generally includable in taxable income to the 
Unitholders as ordinary income for Federal tax purposes upon the receipt of 
serial principal payments on the Bonds, on the sale, maturity or disposition 
of such Bonds by a Trust, and on the sale by a Unitholder of Units, unless a 
Unitholder elects to include the accrued market discount in taxable income as 
such discount accrues.  If a Unitholder does not elect to annually include 
accrued market discount in taxable income as it accrues, deductions for any 
interest expense incurred by the Unitholder which is incurred to purchase or 
carry his Units will be reduced by such accrued market discount.  In general, 
the portion of any interest expense which was not currently deductible would 
ultimately be deductible when the accrued market discount is included in 
income.

Computation of the Unitholder's Tax Basis -- The tax basis of a Unitholder 
with respect to his interest in a Bond is increased by the amount of original 
issue discount (and market discount, if the Unitholder elects to include 
market discount, if any, on the Bonds held by a Trust in income as it 
accrues) thereon properly included in the Unitholder's gross income as 
determined for Federal income tax purposes and reduced by the amount of any 
amortized premium which the Unitholder has properly elected to amortize under 
Section 171 of the Code.  A Unitholder's tax basis in his Units will equal 
his tax basis in his pro rata portion of all of the assets of a Trust.

Recognition of Taxable Gain or Loss upon Disposition of Obligations by a 
Trust or Disposition of Unit -- A Unitholder will recognize taxable capital 
gain (or loss) when all or part of his pro rata interest in a Bond is 
disposed of in a taxable transaction for an amount greater (or less) than his 
tax basis therefor.  Any gain recognized on a sale or exchange and not 
constituting a realization of accrued "market discount," and any loss, will 
generally be capital gain or loss except in the case of a dealer or financial 
institution.  As previously discussed, gain realized on the disposition of 

                                     -20-


<PAGE>

the interest of a Unitholder in any Bond deemed to have been acquired with 
market discount will be treated as ordinary income to the extent the gain 
does not exceed the amount of accrued market discount not previously taken 
into income.  Any capital gain or loss arising from the disposition of a Bond 
by a Trust or the disposition of Units by a Unitholder will be short-term 
capital gain (or loss) unless the Unitholder has held his Units for more than 
one year in which case such capital gain or loss will be long-term.  For 
taxpayers other than corporations, net capital gains are subject to a maximum 
marginal stated tax rate of 28%.  However, it should be noted that 
legislative proposals are introduced from time to time that affect tax rates 
and could affect relative differences at which ordinary income and capital 
gains are taxed.  The tax cost reduction requirements of the Code relating to 
amortization of bond premium may, under some circumstances, result in the 
Unitholder's realizing taxable gain when his Units are sold or redeemed for 
an amount equal to or less than his original cost.

If the Unitholder disposes of a Unit, he is deemed thereby to have disposed 
of his entire pro rata interest in all Trust assets, including his pro rata 
portion of all of the Bonds represented by the Unit.  This may result in a 
portion of the gain, if any, on such sale being taxable as ordinary income 
under the market discount rules (assuming no election was made by the 
Unitholder to include market discount in income as it accrues) as previously 
discussed.

"The Revenue Reconciliation Act of 1993" (the "TAX ACT") raised tax rates on 
ordinary income while capital gains remain subject to a 28% maximum stated 
rate for taxpayers other than corporations.  Because some or all capital 
gains are taxed at a comparatively lower rate under the Tax Act, the Tax Act 
includes a provision that recharacterizes capital gains as ordinary income in 
the case of certain financial transactions that are "conversion transactions" 
effective for transactions entered into after April 30, 1993.  Unitholders 
and prospective investors should consult with their tax advisers regarding 
the potential effect of this provision on their investment in Units.

Foreign Investors -- A Unitholder who is a foreign investor (I.E., an 
investor other than a U.S. citizen or resident of a U.S. corporation, 
partnership, estate or trust) will not be subject to United States federal 
income taxes, including withholding taxes, on interest income (including any 
original issue discount) on, or any gain from the sale or other disposition 
of, his pro rata interest in any Bond or the sale of his Units PROVIDED that 
(i) the interest income or gain is not effectively connected to the conduct 
by the foreign investor of a trade or business within the United States, (ii) 
with respect to any gain, the foreign investor (if an individual) is not 
present in the United States for 183 days or more during his taxable year, 
(iii) the foreign investor provides all certification which may be required 
of his or her status (foreign investors may contact the Sponsor to obtain a 
Form W-8 which must be filed with the Trustee and refiled every three 
calendar years thereafter) and (iv) FURTHER PROVIDED that the exemption from 
withholding for U.S. Federal income taxes for interest on any U.S. Bonds 
shall apply to the extent the bonds were issued after July 18, 1984.  Foreign 
investors should consult their tax advisers with respect to United States tax 
consequences of ownership of Units.  On December 7, 1995 the U.S. Treasury 
Department released proposed legislation that, if adopted, could affect the 
United States federal income taxation of such non-United States Unitholders 
and the portion of the Trust's income allocable to non-United States 
Unitholders.

<PAGE>

In the opinion of Carter, Ledyard & Milburn, special counsel to the Trusts 
for New York tax matters each Trust is not an association taxable as a 
corporation and the income of each Trust will be treated as the income of the 
Unitholders under the existing income tax laws of the State and City of New 
York.

General -- Each Unitholder (other than a foreign investor who has properly 
provided the certifications described above) will be requested to provide the 
Unitholder's taxpayer identification number to the Trustee and to certify 
that the Unitholder has not been notified that payments to the Unitholder are 
subject to back-up withholding.  If the proper taxpayer identification number 
and appropriate certification are not provided with requested, distributions 
by a Trust to such Unitholder will be subject to back-up withholding.

The foregoing discussion relates only to United States federal income taxes 
and applies only to the Trusts which are described in this Prospectus; 
Unitholders may be subject to state and local taxation in other jurisdictions 
(including a foreign investor's country of residence).  Unitholders should 
consult their tax advisers regarding potential state, local, or foreign 
taxation with respect to the Units and the tax treatment of Bonds acquired at 
an original issue discount or market discount and premium, if any.

TRUST OPERATING EXPENSES

No annual advisory fee is charged to the Trusts by the Sponsor.  The Sponsor 
does, however, receive those fees as set forth in "EXPENSE INFORMATION" in 
Part A of this Prospectus for regularly evaluating the Bonds and for 
maintaining surveillance over the portfolio.  (See "UNIT VALUE AND 
EVALUATION.")

The Trustee receives for ordinary recurring services an annual fee for each 
Trust as set forth in "EXPENSE INFORMATION" appearing in Part A of this 
Prospectus.  Each annual fee is per $1,000 principal amount of the underlying 
Bonds in a Trust.  The Trustee's fee may be periodically adjusted in response 
to fluctuations in short-term interest rates (reflecting the cost to the 
Trustee of advancing funds to a Trust to meet scheduled distributions) and 
may be further adjusted in accordance with the cumulative percentage increase 
of the United States Department of Labor's Consumer Price Index entitled "All 
Services Less Rent of Shelter" since the establishment of the Trusts.  The 
Trustee has the use of funds, if any, being held in the Interest and 
Principal Accounts of each Trust for future distributions, payment of 
expenses and redemptions.  These Accounts are non-interest bearing to 
Unitholders.  Pursuant to normal banking procedures, the Trustee benefits 
from the use of funds held therein.  Part of the Trustee's compensation for 
its services to the Trusts is expected to result from such use of these funds.

Premiums for the policies of insurance obtained by the Sponsor or by the Bond 
issuers with respect to the Bonds in the Insured Trusts have been paid in 
full prior to the deposit of the Bonds in the Trusts, and the value of such 
insurance has been included in the evaluation of the Bonds in each Trust and 
accordingly in the Public Offering Price of Units of each Trust.  There are 
no annual continuing premiums for such insurance.

                                     -22-


<PAGE>

All or a portion of the expenses incurred in establishing the Trusts, 
including costs of preparing the registration statement, the trust indenture 
and other closing documents, registering Units with the Securities and 
Exchange Commission and states, the initial audit of each Trust portfolio, 
the initial evaluation, legal fees, the initial fees and expenses of the 
Trustee and any other non-material out-of-pocket expenses, will be paid by 
the Trusts and amortized over the life of such Trusts.  The following are 
additional expenses of the Trusts and, when paid by or are owed to the 
Trustee, are secured by a lien on the assets of the Trust or Trusts to which 
such expenses are allocable:  (1) the expenses and costs of any action 
undertaken by the Trustee to protect the Trusts and the rights and interests 
of the Unitholders; (2) all taxes and other governmental charges upon the 
Bonds or any part of the Trusts (no such taxes or charges are being levied or 
made or, to the knowledge of the Sponsor, contemplated); (3) amounts payable 
to the Trustee as fees for ordinary recurring services and for extraordinary 
non-recurring services rendered pursuant to the Indenture, all disbursements 
and expenses including counsel fees (including fees of counsel which the 
Trustee may retain) sustained or incurred by the Trustee in connection 
therewith; and (4) any losses or liabilities accruing to the Trustee without 
negligence, bad faith or willful misconduct on its part.  The Trustee is 
empowered to sell Bonds in order to pay these amounts if funds are not 
otherwise available in the applicable Interest and Principal Accounts.

The Indenture requires each Trust to be audited on an annual basis at the 
expense of the Trust by independent public accountants selected by the 
Sponsor.  The Trustee shall not be required, however, to cause such an audit 
to be performed if its cost to a Trust shall exceed $.05 per Unit on an 
annual basis.  Unitholders of a Trust covered by an audit may obtain a copy 
of the audited financial statements upon request.

DISTRIBUTIONS TO UNITHOLDERS

Interest received by the Trustee on the Bonds in each Trust, including that 
part of the proceeds of any disposition of Bonds which represents accrued 
interest and including any insurance proceeds representing interest due on 
defaulted Bonds, shall be credited to the "Interest Account" of such Trust 
and all other moneys received by the Trustee shall be credited to the 
"Principal Account" of such Trust.

The pro rata share of cash in the Principal Account in each Trust will be 
computed as of each monthly Record Date and distributions to the Unitholders 
as of such Record Date will be make on or shortly after the fifteenth day of 
the month.  Proceeds received from the disposition, including sale, call or 
maturity, of any of the Bonds and all amounts paid with respect to zero 
coupon bonds and Stripped Obligations will be held in the Principal Account 
and either used to pay for Units redeemed or distributed on the Distribution 
Date following the next monthly Record Date.  The Trustee is not required to 
make a distribution from the Principal Account of any Trust unless the amount 
available for distribution in such account equals at least ten cents per Unit.

The pro rata share of the Interest Account in each Trust will be computed by 
the Trustee each month as of each Record Date and distributions will be make 

                                     -23-


<PAGE>

on or shortly after the fifteenth day of the month to Unitholders of such 
Trust as of the Record Date.  Persons who purchase Units between a Record 
Date and a Distribution Date will receive their first distribution on the 
Distribution Date following the next Record Date under the applicable plan of 
distribution.

See Part A of this Prospectus for details of distributions per Unit of each 
Trust based upon estimated Net Annual Interest Income at the Initial Date of 
Deposit.  The amount of the regular distributions will generally change when 
Bonds are redeemed, mature or are sold or when fees and expenses increase or 
decrease.  For the purpose of minimizing fluctuations in the distributions 
from the Interest Account of a Trust, the Trustee is authorized to advance 
such amounts as may be necessary to provide for interest distributions of 
approximately equal amounts.  The Trustee shall be reimbursed, without 
interest, for any such advances from funds in the Interest Account of such 
Trust.  The Trustee's fee takes into account the costs attributable to the 
outlay of capital needed to make such advances.

As of the first day of each month the Trustee will deduct from the Interest 
Account of a Trust or, to the extent funds are not sufficient therein, from 
the Principal Account of a Trust, amounts needed for payment of expenses of 
such Trust.  The Trustee also may withdraw from said accounts such amount, if 
any, as it deems necessary to establish a reserve for any governmental 
charges payable out of such Trust.  Amounts so withdrawn shall not be 
considered a part of a Trust's assets until such time as the Trustee shall 
withdraw from the Interest Account and the Principal Account of a Trust such 
amounts as may be necessary to cover redemptions of Units of such Trust by 
the Trustee.  Funds which are available for future distributions, redemptions 
and payment of expenses are held in accounts which are non-interest bearing 
to Unitholders and are available for use by the Trustee pursuant to normal 
banking procedures.

Unitholders of a Trust which contains Stripped Treasury Securities should 
note that Stripped Treasury Securities are sold at a deep discount because 
the buyer of those securities obtains only the right to receive a future 
fixed payment on the security and not any rights to periodic interest 
payments thereon.  Purchasers of these Securities acquire, in effect, 
discount obligations that are economically identical to the "zero-coupon 
bonds" that have been issued by corporations.  Zero coupon bonds are debt 
obligations which do not make any periodic payments of interest prior to 
maturity and accordingly are issued at a deep discount.  Under generally 
accepted accounting principles, a holder of a security purchased at a 
discount normally must report as an item of income for financial accounting 
purposes the portion of the discount attributable to the applicable reporting 
period.  The calculation of this attributable income would be made on the 
"interest" method which generally will result in a lesser amount of 
includable income in earlier periods and a corresponding larger amount in 
later periods.  For federal income tax purposes, the inclusion will be on a 
basis that reflects the effective compounding of accrued but unpaid interest 
effectively represented by the discount.  Although this treatment is similar 
to the "interest" method described above, the "interest" method may differ to 
the extent that generally accepted accounting principles permit or require 
the inclusion of interest on the basis of a compounding period other than the 
semi-annual period.  See "TAX STATUS."

<PAGE>

ACCUMULATION PLAN

The Sponsor is also the principal underwriter of several open-end mutual 
funds (the "ACCUMULATION FUNDS") into which Unitholders may choose to 
reinvest Trust distributions.  Unitholders may elect to reinvest principal 
distributions or interest and principal distributions automatically, without 
any sales charge.  Each Accumulation Fund has investment objectives which 
differ in certain respects from those of the Trusts and may invest in 
securities which would not be eligible for deposit in the Trusts.  Further 
information concerning the Accumulation Plan and a list of Accumulation Funds 
is set forth in the Information Supplement of this Prospectus, which may be 
obtained by contacting the Trustee at the phone number listed on the back 
cover of this Prospectus.

Participants may at any time, by so notifying the Trustee in writing, elect 
to change the Accumulation Fund into which their distributions are being 
reinvested, to change from principal only reinvestment to reinvestment of 
both principal and interest or vice versa, or to terminate their 
participation in the Accumulation Plan altogether and receive future 
distributions on their Units in cash.  There will be no charge or other 
penalty for such change of election or termination.  The character of Trust 
distributions for income tax purposes will remain unchanged even if they are 
reinvested in an Accumulation Fund.

REPORTS TO UNITHOLDERS

The Trustee shall furnish Unitholders of a Trust in connection with each 
distribution, a statement of the amount of interest, if any, and the amount 
of other receipts (received since the preceding distribution) being 
distributed, expressed in each case as a dollar amount representing the pro 
rata share of each Unit of a Trust outstanding and a year to date summary of 
all distributions paid on said Units.  Within a reasonable period of time 
after the end of each calendar year, the Trustee shall furnish to each 
person, who at any time during the calendar year was a registered Unitholder 
of a Trust, a statement with respect to such Trust (i) as to the Interest 
Account: interest received (including amounts representing interest received 
upon any disposition of Bonds), deductions for fees and expenses of such 
Trust, redemption of Units and the balance remaining after such distributions 
and deductions, expressed in each case both as a total dollar amount and as a 
dollar amount representing the pro rata share of each Unit outstanding on the 
last business day of such calendar year; (ii) as to the Principal Account: 
the dates of disposition of any Bonds and the net proceeds received therefrom 
(excluding any portion representing accrued interest), the amount paid for 
purchase of Replacement Bonds, the amount paid upon redemption of Units, 
deductions for payment of applicable taxes and fees and expenses of the 
Trustee, and the balance remaining after such distributions and deductions 
expressed both as a total dollar amount and as a dollar amount representing 
the pro rata share of each Unit outstanding on the last business day of such 
calendar year; (iii) a list of the Bonds held and the number of Units 
outstanding on the last business day of such calendar year; (iv) the Unit 
Value based upon the last computation thereof made during such calendar year; 
and (v) amounts actually distributed during such calendar year from the 
Interest Account and from the Principal Account, separately stated, expressed 
both as total dollar amounts and as dollar amounts representing the pro rata 
share of each Unit outstanding.

                                     -25-


<PAGE>

UNIT VALUE AND EVALUATION

The value of each Trust is determined by the Sponsor on the basis of (1) the 
cash on hand in the Trust or moneys in the process of being collected, (2) 
the value of the Bonds in the Trust based on the BID prices of the Bonds and 
(3) interest accrued thereon not subject to collection, LESS (1) amounts 
representing taxes or governmental charges payable out of the Trust and (2) 
the accrued expenses of the Trust.  The result of such computation is divided 
by the number of Units of the Trust outstanding as of the date thereof to 
determine the per Unit value ("UNIT VALUE") of such Trust.  The Sponsor may 
determine the value of the Bonds in each Trust (1) on the basis of current 
BID prices of the Bonds obtained from dealers or brokers who customarily deal 
in bonds comparable to those held by the Trust, (2) if bid prices are not 
available for any of the Bonds, on the basis of bid prices for comparable 
bonds, (3) by causing the value of the Bonds to be determined by others 
engaged in the practice of evaluating, quoting or appraising comparable bonds 
or (4) by any combination of the above.  Although the Unit Value of each 
Trust is based on the BID prices of the Bonds, the Units are sold initially 
to the public at the Public Offering Price based on the OFFERING prices of 
the Bonds.

Because the insurance obtained by the Sponsor or by the issuers of Bonds with 
respect to the Bonds in the Insured Trusts is effective so long as such Bonds 
are outstanding, such insurance will be taken into account in determining the 
bid and offering prices of such Bonds and therefore some value attributable 
to such insurance will be included in the value of Units of Trusts that 
include such Bonds.

DISTRIBUTIONS OF UNITS TO THE PUBLIC

Nuveen, in addition to being the Sponsor, is the sole Underwriter of the 
Units.  It is the intention of the Sponsor to qualify Units of the Trusts for 
sale under the laws of substantially all of the states of the United States 
of America.

Promptly following the deposit of Bonds in exchange for Units of the Trusts, 
it is the practice of the Sponsor to place all of the Units as collateral for 
a letter or letters of credit from one or more commercial banks under an 
agreement to release such Units from time to time as needed for distribution. 
 Under such an arrangement the Sponsor pays such banks compensation based on 
the then current interest rate.  This is a normal warehousing arrangement 
during the period of distribution of the Units to public investors.  To 
facilitate the handling of transactions, sales of Units shall be limited to 
transactions involving a minimum of either $5,000 or 50 Units, whichever is 
less.  The Sponsor reserves the right to reject, in whole or in part, any 
order for the purchase of Units.

The Sponsor plans to allow a discount to brokers and dealers in connection with 
the primary distribution of Units and also in secondary market transactions.  
The amounts of such discounts are set forth in Part A of this Prospectus.

The Sponsor currently intends to maintain a secondary market for Units of each 
Trust.  See "MARKET FOR UNITS."  

                                     -26-


<PAGE>

The Sponsor reserves the right to change the amounts of the dealer concessions 
set forth in Part A of this Prospectus from time to time.

Registered investment advisers, certified financial planners and registered 
broker-dealers who in each case either charge periodic fees for financial 
planning, investment advisory or asset management services, or provide such 
services in connection with the establishment of an investment account for 
which a comprehensive "wrap fee" charge is imposed, and bank trust 
departments investing funds over which they exercise exclusive discretionary 
investment authority and that are held in a fiduciary, agency, custodial or 
similar capacity, are not entitled to receive any dealer concession for any 
sales made to investors which qualified as "Discounted Purchases" during the 
primary or secondary market.  (See "PUBLIC OFFERING PRICE.")

Certain commercial banks are making Units of the Trusts available to their 
customers on an agency basis.  A portion of the sales charge paid by these 
customers is retained by or remitted to the banks in the amounts shown in the 
above table.  The Glass-Steagall Act prohibits banks from underwriting Trust 
Units; the Act does, however, permit certain agency transactions and banking 
regulators have not indicated that these particular agency transactions are 
not permitted under the Act.  In Texas and in certain other states, any bank 
making Units available must be registered as a broker-dealer under state law.

OWNERSHIP AND TRANSFER OF UNITS

The ownership of Units is evidenced by book entry positions recorded on the 
books and records of the Trustee unless the Unitholder expressly requests 
that the purchased Units be evidenced in Certificate form.  The Trustee is 
authorized to treat as the owner of Units that person who at the time is 
registered as such on the books of the Trustee.  Any Unitholder who holds a 
Certificate may change to book entry ownership by submitting to the Trustee 
the Certificate along with a written request that the Units represented by 
such Certificate be held in book entry form.  Likewise, a Unitholder who 
holds Units in book entry form may obtain a Certificate for such Units by 
written request to the Trustee.  Units may be held in denominations of one 
Unit or any multiple or fraction thereof.  Fractions of Units are computed to 
three decimal places.  Any Certificates issued will be numbered serially for 
identification, and are issued in fully registered form, transferable only on 
the books of the Trustee.  Book entry Unitholder will receive a Book Entry 
Position Confirmation reflecting their ownership.

Units are transferable by making a written request to the Trustee and, in the 
case of Units evidenced by Certificate(s), by presenting and surrendering 
such Certificate(s) to the Trustee, at its address listed on the back cover 
of this Part B of the Prospectus, properly endorsed or accompanied by a 
written instrument or instruments of transfer.  The Certificate(s) should be 
sent registered or certified mail for the protection of the Unitholders.  
Each Unitholder must sign such written request, and such Certificate(s) or 
transfer instrument, exactly as his name appears on (a) the face of the 
Certificate(s) representing the Units to be transferred, or (b) the Book 
Entry Position Confirmation(s) relating to the Units to be transferred.  Such 

                                     -27-


<PAGE>

signature(s) must be guaranteed by a guarantor acceptable to the Trustee.  In 
certain instances the Trustee may require additional documents such as, but 
not limited to, trust instruments, certificates of death, appointments as 
executor or administrator or certificates of corporate authority.  Mutilated 
Certificates must be surrendered to the Trustee in order for a replacement 
Certificate to be issued.  Although at the date hereof no charge is made and 
none is contemplated, a Unitholder may be required to pay $2.00 to the 
Trustee for each Certificate reissued or transfer of Units requested and to 
pay any governmental charge which may be imposed in connection therewith.

Replacement of lost, stolen or destroyed certificates.

To obtain a new Certificate replacing one that has been lost, stolen, or 
destroyed, the Unitholder must furnish the Trustee with sufficient 
indemnification and pay such expenses as the Trustee may incur.  This 
indemnification must be in the form of an Open Penalty Bond of 
Indemnification.  The premium for such an indemnity bond may vary, but 
currently amounts to 1% of the market value of the Units represented by the 
Certificate.  In the case however, of a Trust as to which notice of 
termination has been given, the premium currently amounts to 0.5% of the 
market value of the Units represented by such Certificate.

REDEMPTION

Unitholders may redeem all or a portion of their Units by (1) making a 
written request for such redemption (book entry Unitholders may use the 
redemption form on the reverse side of their Book Entry Position 
Confirmation) to the Trustee at its address listed on the back cover of this 
Part B of the Prospectus (redemptions of 1,000 Units or more will require a 
signature guarantee), (2) in the case of Units evidenced by a Certificate, by 
also tendering such Certificate to the Trustee, duly endorsed or accompanied 
by proper instruments of transfer with signatures guaranteed as explained 
above, or provide satisfactory indemnity required in connection with lost, 
stolen or destroyed Certificates and (3) payment of applicable governmental 
charges, if any.  Certificates should be sent only by registered or certified 
mail to minimize the possibility of their being lost or stolen.  (See 
"OWNERSHIP AND TRANSFER OF UNITS.")  No redemption fee will be charged.  A 
Unitholder may authorize the Trustee to honor telephone instructions for the 
redemption of Units held in book entry form.  Units represented by 
Certificates may not be redeemed by telephone.  The proceeds of Units 
redeemed by telephone will be sent by check either to the Unitholder at the 
address specified on his account or to a financial institution specified by 
the Unitholder for credit to the account of the Unitholders.  A Unitholder 
wishing to use this method of redemption must complete a Telephone Redemption 
Authorization Form and furnish the Form to the Trustee.  Telephone Redemption 
Authorization Forms can be obtained from a Unitholder's registered 
representative or by calling the Trustee.  Once the completed Form is on 
file, the Trustee will honor telephone redemption requests by any authorized 
person.  The time a telephone redemption request is received determines the 
"date of tender" as discussed below.  The redemption proceeds will be mailed 
within three business days following the telephone redemption request.  Only 
Units held in the name of individuals may be redeemed by telephone; accounts 
registered in broker name, or accounts of corporations or fiduciaries 
(including among others, trustees, guardians, executors and administrators) 
may not use the telephone redemption privilege.

                                     -28-


<PAGE>

On the third business day following the date of tender, the Unitholder will 
be entitled to receive in cash for each Unit tendered an amount equal to the 
Unit Value of such Trust determined by the Trustee, as of 4:00 p.m. eastern 
time, or as of any earlier closing time on a day on which the Exchange is 
scheduled in advance to close at such earlier time, on the date of tender as 
defined hereafter, plus accrued interest to, but not including, the third 
business day after the date of tender ("REDEMPTION PRICE").  The price 
received upon redemption may be more or less than the amount paid by the 
Unitholder depending on the value of the Bonds on the date of tender.  
Unitholders should check with the Trustee or their broker to determine the 
Redemption Price before tendering Units.

The "DATE OF TENDER" is deemed to be the date on which the request for 
redemption of Units is received in proper form by the Trustee, except that as 
regards a redemption request received after 4:00 p.m. eastern time, or as of 
any earlier closing time on a day on which the Exchange is scheduled in 
advance to close at such earlier time, or on any day on which the Exchange is 
normally closed, the date of tender is the next day on which such Exchange is 
normally open for trading and such request will be deemed to have been made 
on such day and the redemption will be effected at the Redemption Price 
computed on that day.

Accrued interest paid on redemption shall be withdrawn from the Interest 
Account of the appropriate Trust or, if the balance therein is insufficient, 
from the Principal Account of such Trust.  All other amounts paid on 
redemption shall be withdrawn from the Principal Account.  The Trustee is 
empowered to sell underlying Bonds of a Trust in order to make funds 
available for redemption.  (See "REMOVAL OF BONDS FROM THE TRUSTS.")  Units 
so redeemed shall be cancelled.  To the extent that Bonds are sold from the 
Trusts, the size and diversity of such Trust will be reduced.  Such sales may 
be required at a time when Bonds would not otherwise be sold and might result 
in lower prices than might otherwise be realized.

The Redemption Price is determined on the basis of the BID prices of the 
Bonds in each Trust, while the initial Public Offering Price of Units will be 
determined on the basis of the OFFERING prices of the Bonds as of 4:00 p.m. 
eastern time on any day on which the Exchange is normally open for trading, 
or as of any earlier closing time on a day on which the Exchange is scheduled 
in advance to close at such earlier time, and such determination is made.  As 
of any given time, the difference between the bid and offering prices of such 
Bonds may be expected to average 1/2% to 2% of principal amount.  In the case 
of actively traded Bonds , the difference may be as little as 1/4 to 1/2 of 
1%, and in the case of inactively traded Bonds such difference usually will 
not exceed 3%.

The right of redemption may be suspended and payment postponed (1) for any 
period in which the New York Stock Exchange is closed, other than customary 
weekend and holiday closings or for any period during which the Securities 
and Exchange Commission determines that trading on the New York Stock 
Exchange is restricted, (2) for any period during which an emergency exists, 
as a result of which disposal or evaluation of the Securities is not 
reasonably practicable, or (3) for such other periods as the Securities and 
Exchange Commission may by order permit.

                                     -29-


<PAGE>

Under regulations issued by the Internal Revenue Service, the Trustee will be 
required to withhold a specified percentage of the principal amount of a Unit 
redemption if the Trustee has not been furnished the redeeming Unitholder's 
tax identification number in the manner required by such regulations.  Any 
amount so withheld is transmitted to the Internal Revenue Service and may be 
recovered by the Unitholder only when filing his or her tax return.  Under 
normal circumstances the Trustee obtains the Unitholder's tax identification 
number from the selling broker at the time the Certificate or Book Entry 
Return Confirmation is issued, and this number is printed on the Certificate 
or Book Entry Return Confirmation and on distribution statements.  If a 
Unitholder's tax identification number does not appear as described above, or 
if it is incorrect, the Unitholder should contact the Trustee before 
redeeming Units to determine what action, if any, is required to avoid this 
"back-up withholding."

PURCHASE OF UNITS BY THE SPONSOR

The Trustee will notify the Sponsor of any tender of Units for redemption.  
If the Sponsor's bid in the secondary market at that time equals or exceeds 
the Redemption Price it may purchase such Units by notifying the Trustee 
before the close of business on the second succeeding business day and by 
making payment therefor to the Unitholder not later than the day on which 
payment would otherwise have been made by the Trustee.  (See "REDEMPTION.")  
The Sponsor's current practice is to bid at the Redemption Price in the 
secondary market.  Units held by the Sponsor may be tendered to the Trustee 
for redemption as any other Units.

REMOVAL OF BONDS FROM THE TRUSTS

Bonds will be removed from a Trust as they mature.  The Indenture also 
empowers the Trustee to sell Bonds for the purpose of redeeming Units 
tendered by any Unitholder, and for the payment of expenses for which income 
may not be available.  Under the Indenture, the Sponsor is obligated to 
provide the Trustee with a current list of Bonds in each Trust to be sold in 
such circumstances.  In deciding which Bonds should be sold the Sponsor 
intends to consider, among other things, such factors as: (1) market 
conditions; (2) market prices of the Bonds; (3) the effect on income 
distributions to Unitholders of the sale of various Bonds; (4) the effect on 
principal amount of underlying Bonds per Unit of the sale of various Bonds; 
(5) the financial condition of the issuers; and (6) the effect of the sale of 
various Bonds on the investment character of the Trust.  Such sales, if 
required, could result in the sale of Bonds by the Trustee at prices less 
than original cost to the Trust.  To the extent Bonds are sold, the size and 
diversity of such Trust will be reduced.

In addition, the Sponsor is empowered to direct the Trustee to liquidate 
Bonds upon the happening of certain other events, such as default in the 
payment of principal and/or interest, an action of the issuer that will 
adversely affect its ability to continue payment of the principal of and 
interest on its Bonds, or an adverse change in market, revenue or credit 
factors affecting the investment character of the Bonds.  If a default in the 
payment of the principal of and/or interest on any of the Bonds occurs, and 

                                     -30-


<PAGE>

if the Sponsor fails to instruct the Trustee whether to sell or continue to 
hold such Bonds within 30 days after notification by the Trustee to the 
Sponsor of such default, the Indenture provides that the Trustee shall 
liquidate said Bonds forthwith and shall not be liable for any loss so 
incurred.  The Sponsor may also direct the Trustee to liquidate Bonds in a 
Trust if the Bonds in the Trust are the subject of an advanced refunding 
generally considered to be when refunding bonds are issued and the proceeds 
thereof are deposited in irrevocable trust to retire the refunded Bonds on 
their redemption date.

Except as stated in "COMPOSITION OF THE TRUST" regarding the deposit of 
additional bonds or the limited right of substitution of Replacement Bonds 
for Failed Bonds, and except for refunding Bonds that may be exchanged for 
Bonds under certain conditions specified in the Indenture, the Indenture does 
not permit either the Sponsor or the Trustee to acquire or deposit bonds 
either in addition to, or in substitution for, any of the Bonds initially 
deposited in a Trust.

INFORMATION ABOUT THE TRUSTEE

The Trustee and its address are stated on the back cover of this Part B of 
the Prospectus.  The Trustee is subject to supervision and examination by the 
Federal Deposit Insurance Corporation, the Board of Governors of the Federal 
Reserve System and either the Comptroller of the Currency or state banking 
authorities.

Limitations on Liabilities of Sponsor and Trustee

The Sponsor and the Trustee shall be under no liability to Unitholders for 
taking any action or for refraining from any action in good faith pursuant to 
the Indenture, or for errors in judgment, but shall be liable only for their 
own negligence, lack of good faith or willful misconduct.  The Trustee shall 
not be liable for depreciation or loss incurred by reason of the sale by the 
Trustee of any of the Bonds.  In the event of the failure of the Sponsor to 
act under the Indenture, the Trustee may act thereunder and shall not be 
liable for any action taken by it in good faith under the Indenture.

The Trustee shall not be liable for any taxes or other governmental charges 
imposed upon or in respect of the Bonds or upon the interest thereon or upon 
it as Trustee under the Indenture or upon or in respect of any Trust which 
the Trustee may be required to pay under any present or future law of the 
United States of America or of any other taxing authority having 
jurisdiction.  In addition, the Indenture contains other customary provisions 
limiting the liability of the Trustee.

Successor Trustees and Sponsors

The Trustee or any successor trustee may resign by executing an instrument of 
resignation in writing and filing same with the Sponsor and mailing a copy of 
a notice of resignation to all Unitholders then of record.  Upon receiving 
such notice, the Sponsor is required to promptly appoint a successor trustee. 
 If the Trustee becomes incapable of acting or is adjudged a bankrupt or 
insolvent, or a receiver or other public officer shall take charge of its 

                                     -31-


<PAGE>

property or affairs, the Sponsor may remove the Trustee and appoint a 
successor by written instrument.  The resignation or removal of a trustee and 
the appointment of a successor trustee shall become effective only when the 
successor trustee accepts its appointment as such.  Any successor trustee 
shall be a corporation authorized to exercise corporate trust powers, having 
capital, surplus and undivided profits of not less than $5,000,000.  Any 
corporation into which a trustee may be merged or with which it may be 
consolidated, or any corporation resulting from any merger or consolidation 
to which a trustee shall be a party, shall be the successor trustee.

If upon resignation of a trustee no successor has been appointed and has 
accepted the appointment within 30 days after notification, the retiring 
trustee may apply to a court of competent jurisdiction for the appointment of 
a successor.

If the Sponsor fails to undertake any of its duties under the Indenture, and 
no express provision is made for action by the Trustee in such event, the 
Trustee may, in addition to its other powers under the Indenture (1) appoint 
a successor sponsor or (2) terminate the Indenture and liquidate the Trusts.

To help advisers and investors better understand and more efficiently use an 
investment in the Trusts to reach their investment goals, the Sponsor may 
advertise and create specific investment programs and systems.  For example, 
such activities may include presenting information on how to use an 
investment in the Trust, alone or in combination with an investment in other 
mutual funds or unit investment trusts sponsored by Nuveen, to accumulate 
assets for future education needs or periodic payments such as insurance 
premiums.  The Trusts' sponsor may produce software or additional sales 
literature to promote the advantages of using the Trusts to meet these and 
other specific investor needs.

OTHER INFORMATION

Amendment of Indenture

The Indenture may be amended by the Trustee and the Sponsor without the 
consent of any of the Unitholders (1) to cure any ambiguity or to correct or 
supplement any provision thereof which may be defective or inconsistent, or 
(2) to make such other provisions as shall not adversely affect the 
Unitholders, provided, however, that the Indenture may not be amended to 
permit the deposit or acquisition of bonds either in addition to, or in 
substitution for any of the Bonds initially deposited in any Trust except as 
stated in "COMPOSITION OF THE TRUSTS" regarding the creation of additional 
Units and the limited right of substitution of Replacement Bonds and except 
for the substitution of refunding bonds under certain circumstances.  The 
Trustee shall advise the Unitholders of any amendment promptly after 
execution thereof..i.Indenture, Amendment of;

Termination of Indenture

Each Trust may be liquidated at any time by written consent of 100% of the 
Unitholders or by the Trustee when the value of such Trust, as shown by any 
evaluation, is less than 20% of the original principal amount of such Trust 
and will be liquidated by the Trustee in the event that Units not yet sold 
aggregating more than 60% of the Units originally created are tendered for 
redemption by the Sponsor thereby reducing the net worth of such Trust to 
less than 40% of the principal amount of the Bonds originally deposited in 
the portfolio.  (See "PERFORMANCE INFORMATION" appearing in Part A of this 
Prospectus.)  The sale of Bonds from the Trusts upon termination may result 
in realization of a lesser amount than might otherwise be realized if such 
sale were not required at such time.  For this reason, among others, the 
amount realized by a Unitholder upon termination may be less than the 
principal amount of Bonds originally represented by the Units held by such 
Unitholder.  The Indenture will terminate upon the redemption, sale or other 
disposition of the last Bond held thereunder, but in no event shall it 
continue beyond the end of the calendar year preceding the twentieth 
anniversary of its execution for Long-Term, Long Intermediate, and 
Intermediate Trusts or beyond the end of the calendar year preceding the 
tenth anniversary of its execution for Short Intermediate and Short Term 
Trusts.

Written notice of any termination specifying the time or times at which 
Unitholders may surrender their Certificates, if any, for cancellation shall 
be given by the Trustee to each Unitholder at the address appearing on the 
registration books of a Trust maintained by the Trustee.  Within a reasonable 
time thereafter, the Trustee shall liquidate any Bonds in the Trust then held 
and shall deduct from the assets of the Trust any accrued costs, expenses or 
indemnities provided by the Indenture which are allocable to such Trust, 
including estimated compensation of the Trustee and costs of liquidation and 
any amounts required as a reserve to provide for payment of any applicable 
taxes or other governmental charges.  The Trustee shall then distribute to 
Unitholders of such Trust their pro rata share of the balance of the Interest 
and Principal Accounts.  With such distribution, the Unitholders shall be 
furnished a final distribution statement, in substantially the same form as 

                                     -33-


<PAGE>

the annual distribution statement, of the amount distributable.  At such time 
as the Trustee in its sole discretion shall determine that any amounts held 
in reserve are no longer necessary, it shall make distribution thereof to 
Unitholders in the same manner.

ACCUMULATION PLAN

The Sponsor, John Nuveen & Co. Incorporated, is also the principal 
underwriter of the Accumulation Funds listed in the following table.  Each of 
these funds is an open-end, diversified management investment company into 
which Unitholders may choose to reinvest Trust distributions automatically, 
without any sales charge.  Unitholders may reinvest both interest and 
principal distributions or principal distributions only.  Each Accumulation

Each person who purchases Units of a Trust may become a participant in the 
Accumulation Plan and elect to have his or her distributions on Units of the 
Trust invested directly in shares of one of the Accumulation Funds. 
Reinvesting Unitholders may select any interest distribution plan.  
Thereafter, each distribution of interest income or principal on the 
participant's Units (principal only in the case of a Unitholder who has 
chosen to reinvest only principal distributions) will, on the applicable 
distribution date, or the next day on which the New York Stock Exchange is 
nominally open ("BUSINESS DAY") if the distribution date is not a business 
day, automatically be received by the transfer agent for each of the 
Accumulation Funds, on behalf of such participant and applied on that date to 
purchase shares (or fractions thereof) of the Accumulation Fund chosen at net 
asset value as computed as of 4:00 p.m. eastern time on each such date.  All 
distributions will be reinvested in the Accumulation Fund chosen and no part 
thereof will be retained in a separate account.  These purchases will be made 
without a sales charge.

The Transfer Agent of the Accumulation Fund will mail to each participant in 
the Accumulation Plan a quarterly statement containing a record of all 
transactions involving purchases of Accumulation Fund shares (or fractions 
thereof) with Trust interest distributions or as a result of reinvestment of 

                                     -3-


<PAGE>

Accumulation Fund dividends.  Any distribution of principal used to purchase 
shares of an Accumulation Fund will be separately confirmed by the Transfer 
Agent.  Unitholders will also receive distribution statements from the 
Trustee detailing the amounts transferred to their Accumulation Fund accounts.

Participants may at any time, by so notifying the Trustee in writing, elect 
to change the Accumulation Fund into which their distributions are being 
reinvested, to change from principal only reinvestment to reinvestment of 
both principal and interest or vice versa, or to terminate their 
participation in the Accumulation Plan altogether and receive future 
distributions on their Units in cash.  There will be no charge or other 
penalty for such change of election or termination.  The character of Trust 
distributions for income tax purposes will remain unchanged even if they are 
reinvested in an Accumulation Fund.

investment in the Trust to reach their investment goals, the Trust's sponsor, 
John Nuveen & Co. Incorporated, may advertise and create specific investment 
programs and systems.  For example, such activities may include presenting 
information on how to use an investment in the Trust, alone or in combination 
with an investment in other mutual funds or unit investment trusts sponsored 
by Nuveen, to accumulate assets for future education needs or periodic 
payments such as insurance premiums.  The Trust's sponsor may produce 
software or additional sales literature to promote the advantages of using 
the Trust to meet these and other specific investor needs.

The Sponsor offers a program of advertising support to registered 
broker-dealer firms, banks and bank affiliates ("FIRMS") that sell Trust 
Units or shares of Nuveen Open-End Mutual Funds (excluding money-market 
funds) ("FUNDS").  Under this program, the Sponsor will pay or reimburse the 
Firm for up to one half of specified media costs incurred in the placement of 
advertisements which jointly feature the Firm and the Nuveen Funds and 
Trusts.  Reimbursements to the Firm will be based on the number of the Firm's 
registered representatives who have sold Fund Shares and/or Trust Units 
during the prior calendar year according to an established schedule.  
Reimbursements under this program will be made by the Sponsor and not by the 
Funds or Trusts.

DESCRIPTION OF RATINGS

STANDARD & POOR'S CORPORATION.  A description of the applicable Standard & 
Poor's Corporation rating symbols and their meanings follows:

A Standard & Poor's rating is a current assessment of the creditworthiness of 
an obligor with respect to a specific debt obligation.  This assessment may 
take into consideration obligors such as guarantors, insurers or lessees.

The rating is not a recommendation to purchase, sell or hold a security, 
inasmuch as it does not comment as to market price or suitability for a 
particular investor.

The ratings are based on current information furnished by the issuer or 
obtained by Standard & Poor's from other sources it considers reliable.  
Standard & Poor's does not perform an audit in connection with any rating and 
may, on occasion, rely on unaudited financial information.  The ratings may 
be changed, suspended or withdrawn as a result of changes in, or 
unavailability of, such information, or for other circumstances.

The ratings are based, in varying degrees, on the following considerations: 

  I.  Likelihood of default_capacity and willingness of the obligor as to 
the timely payment of interest and repayment of principal in accordance with 
the terms of the obligation;

  II.  Nature of and provisions of the obligation;

  III. Protection afforded by, and relative position of, the obligation in 
the event of bankruptcy, reorganization or other arrangements under the laws of
bankruptcy and other laws affecting creditors' rights.

AAA--This is the highest rating assigned by Standard & Poor's to a debt 
obligation.  Capacity to pay interest and repay principal is extremely strong.

AA--Bonds rated AA have a very strong capacity to pay interest and repay 
principal, and differ from the highest rated issues only in small degree.

A--Bonds rated A have a strong capacity to pay interest and repay principal, 
although they are somewhat more susceptible to the adverse effects of changes 
in circumstances and economic conditions than bonds in higher rated 
categories.

BBB--Bonds rated BBB are regarded as having an adequate capacity to pay 
interest and repay principal.  Whereas they normally exhibit adequate 
protection parameters, adverse economic conditions or changing circumstances 
are more likely to lead to a weakened capacity to pay interest and repay 
principal for bonds in this category than for bonds in the higher rated 
categories.

                                     -6-


<PAGE>

PLUS (+) OR MINUS (-):  The ratings from "AA" to "BB" may be modified by the 
addition of a plus or minus sign to show relative standing within the major 
rating categories.

PROVISIONAL RATINGS:  The letter "p" indicates that the rating is 
provisional.  A provisional rating assumes the successful completion of the 
project being financed by the issuance of the bonds being rated and indicates 
that payment of debt service requirements is largely or entirely dependent 
upon the successful and timely completion of the project.  This rating, 
however, while addressing credit quality subsequent to completion of the 
project, makes no comment on the likelihood of, or the risk of default upon 
failure of, such completion.  Accordingly, the investor should exercise his 
own judgment with respect to such likelihood and risk.

NOTE RATINGS:  A Standard & Poor's note rating reflects the liquidity concerns 
and market access risks unique to notes.  Notes due in 3 years or less will 
likely receive a note rating.  Notes maturing beyond 3 years will most likely 
receive a long-term debt rating.

Note rating symbols are as follows:

SP-1  Very strong or strong capacity to pay principal and interest.  Those 
issues determined to possess overwhelming safety characteristics will be 
given a plus (+) designation.

SP-2  Satisfactory capacity to pay principal and interest.

RATINGS OF INSURED TRUST UNITS

A Standard & Poor's rating on the units of an insured investment trust 
(hereinafter referred to collectively as "UNITS" and "TRUSTS") is a current 
assessment of creditworthiness with respect to the investment held by such 
trust.  This assessment takes into consideration the financial capacity of 
the issuers and of any guarantors, insurers, lessees or mortgagors with 
respect to such investments.  The assessment, however, does not take into 
account the extent to which trust expenses or portfolio asset sales for less 
than the trust purchase price will reduce payment to the unitholder of the 
interest and principal required to be paid on the portfolio assets.  In 
addition, the rating is not a recommendation to purchase, sell or hold units, 
inasmuch as the rating does not comment as to market price of the units or 
suitability for a particular investor.

Units rated "AAA" are composed exclusively of assets that are rated "AAA" by 
Standard & Poor's and/or certain short-term investments.  Standard & Poor's 
defines its AAA rating for such assets as the highest rating assigned by 
Standard & Poor's to a debt obligation.  Capacity to pay interest and repay 
principal is very strong.  However, unit ratings may be subject to revision 
or withdrawal at any time by Standard & Poor's and each rating should be 
evaluated independently of any other rating.

MOODY'S INVESTORS SERVICE, INC.  A brief description of the applicable 
Moody's Investors Service, Inc. rating symbols and their meanings follows:

                                     -7-


<PAGE>

Aaa--Bonds which are rated Aaa are judged to be the best quality.  They carry 
the smallest degree of investment risk and are generally referred to as "gilt 
edge."  Interest payments are protected by a large or by an exceptionally 
stable margin and principal is secure.  While the various protective elements 
are likely to change, such changes as can be visualized are most unlikely to 
impair the fundamentally strong position of such issues.  Their safety is so 
absolute that, with the occasional exception of oversupply in a few specific 
instances, characteristically, their market value is affected solely by money 
market fluctuations.

Aa--Bonds which are rated Aa are judged to be of high quality by all 
standards.  Together with the Aaa group they comprise what are generally 
known as high grade bonds.  They are rated lower than the best bonds because 
margins of protection may not be as large as in Aaa securities or 
fluctuations of protective elements may be of greater amplitude or there may 
be other elements present which make the long-term risks appear somewhat 
larger than in Aaa securities.  Their market value is virtually immune to all 
but money market influences, with the occasional exception of oversupply in a 
few specific instances.

A--Bonds which are rated A possess many favorable investment attributes and 
are to be considered as upper medium grade obligations.  Factors giving 
security to principal and interest are considered adequate, but elements may 
be present which suggest a susceptibility to impairment sometime in the 
future.  The market value of A-rated bonds may be influenced to some degree 
by economic performance during a sustained period of depressed business 
conditions, but, during periods of normalcy, A-rated bonds frequently move in 
parallel with Aaa and Aa obligations, with the occasional exception of 
oversupply in a few specific instances.

Moody's bond rating symbols may contain numerical modifiers of a generic 
rating classification.  The modifier 1 indicates that the bond ranks at the 
high end of its category; the modifier 2 indicates a mid-range ranking; and 
the modifier 3 indicates that the issue ranks in the lower end of its generic 
rating category.

Baa--Bonds which are rated Baa are considered as medium grade obligations, 
i.e., they are neither highly protected nor poorly secured.  Interest 
payments and principal security appear adequate for the present but certain 
protective elements may be lacking or may be characteristically unreliable 
over any great length of time.  Such bonds lack outstanding investment 
characteristics and in fact have speculative characteristics as well.  The 
market value of Baa-rated bonds is more sensitive to changes in economic 
circumstances, and aside from occasional speculative factors applying to some 
bonds of this class, Baa market valuations move in parallel with Aaa, Aa and 
A obligations during periods of economic normalcy, except in instances of 
oversupply.

Con. (--)--Bonds for which the security depends upon the completion of some 
act or the fulfillment of some condition are rated conditionally.  These are 
bonds secured by (a) earnings of projects under construction, (b) earnings of 
projects unseasoned in operation experience, (c) rentals which begin when 

                                     -8-


<PAGE>

facilities are completed, or (d) payments to which some other limiting 
condition attaches.  Parenthetical rating denotes probable credit stature 
upon completion of construction or elimination of basis of condition.

Note Ratings:

MIG 1--This designation denotes best quality.  There is present strong 
protection by established cash flows, superior liquidity support or 
demonstrated broad-based access to the market for refinancing.

MIG 2--This designation denotes high quality.  Margins of protection are 
ample although not so large as in the preceding group.
